Which term describes choosing different paths based on conditions?

• A. Iteration
• B. Selection
• C. Pre-condition loops
• D. Counting

Answer: (B)

Choosing different paths based on conditions is about branching, where the program decides which block to run next. The term that describes this decision point is selection. It’s implemented with structures like if…else, which tests a condition and executes one set of instructions if true, a different set if false. This contrasts with iteration, which is about repeating a block of instructions, and with counting, which is simply using a variable to keep track of a number. Pre-condition loops are a kind of repetition that checks the condition before each iteration, not about choosing between different paths. So selection best captures the idea of selecting one path or another based on a condition.
