Final Answer:
The statement given "An algorithm is a logical and rational step-by-step solution to a problem." is true because algorithms provide a systematic approach for problem-solving. Option A is answer.
Step-by-step explanation:
An algorithm is a systematic, well-defined procedure that follows a sequence of logical steps to solve a particular problem or perform a specific task. It is designed to produce a correct and efficient solution, breaking down the problem into smaller, manageable steps.
The correctness of an algorithm is ensured by its logical structure, which adheres to principles such as clarity, precision, and effectiveness.
Therefore, the statement accurately reflects the nature and purpose of algorithms.
Option A is answer.
