Final answer:
The correct answer to match the programming paradigms with their characteristics is C. a - iv, b - iii, c - i, d - ii.
Step-by-step explanation:
The student has asked to match programming paradigms with their characteristics. Here are the correct matches: Imperative programming is characterized by command-based, procedural code, where programmers write sequences of commands for the computer to perform.
Object-oriented programming involves the use of abstract data types, encapsulation, inheritance, and polymorphism and is thus about structuring programs as a collection of objects. Logic programming is declarative, uses a clausal representation, and is based on theorem proving, where the computer searches through a space of possible solutions.
Functional programming is characterized by being side-effect free and declarative, focusing on the evaluation of expressions rather than execution of commands. Therefore, the correct answer to the student's question is C. a - iv, b - iii, c - i, d - ii.
