Comprehensive and Detailed Explanation From Exact Extract:

Object-oriented programming (OOP) languages are distinguished by their use of objects, which encapsulate data and behavior, and support features like inheritance, polymorphism, and encapsulation. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide), this object-based approach is unique to OOP and not inherent to procedural or functional paradigms.

Option A: "The language is optimized for recursive programming." This is incorrect. Recursion is a technique supported by many languages across paradigms, including procedural (e.g., C), functional (e.g., Haskell), and object-oriented (e.g., Java). It is not unique to OOP.

Option B: "The language is based on the concept of modular programming and the calling of a subroutine." This is incorrect. Modular programming and subroutines (functions or procedures) are central to procedural languages (e.g., C) and also supported in functional languages. While OOP languages support modularity, this is not their distinguishing feature.

Option C: "The language treats programs as evaluating mathematical functions." This is incorrect. This describes functional programming languages (e.g., Haskell, Lisp), which emphasize immutability and function evaluation, not OOP.

Option D: "The language supports decomposing a program into objects that interact with one another." This is correct. OOP languages (e.g., Java, C++, Python) are characterized by organizing code into objects that encapsulate data and methods, interacting through messages or method calls. This is not a feature of procedural (e.g., C) or functional (e.g., Scheme) languages, which focus on procedures or functions, respectively.

Comprehensive and Detailed Explanation From Exact Extract:

Determining the mathematical operations (e.g., addition, subtraction, multiplication) for a calculator program involves defining what the program should do (requirements) and planning how to achieve it (technical specifications). According to foundational programming principles, this spans the analysis and design phases in the Waterfall methodology.

Waterfall Phases Analysis:

Analysis: The developer identifies the requirements, such as which operations the calculator must support (e.g., “must perform addition, subtraction, etc.”).

Design: The developer specifies how these operations will be implemented (e.g., defining functions like add(), subtract(), or their algorithms).

Implementation: Codes the operations.

Testing: Verifies the operations work correctly.

Option A: "Analysis and design." This is correct. Analysis determines the operations needed (requirements), and design outlines their technical specifications (e.g., function signatures or algorithms).

Option B: "Design and implementation." This is incorrect. Implementation involves coding the operations, not determining which operations are needed.

Option C: "Implementation and testing." This is incorrect. These phases occur after the operations are determined, focusing on coding and verification.

Option D: "Design and testing." This is incorrect. Testing verifies the implemented operations, not their determination.
