Which control construct is used to make decisions in programming?

The correct choice is conditional statements because they provide a way for a program to execute different code segments based on specific conditions. When a condition is evaluated, it can result in either true or false, allowing the program to take different paths of execution. This decision-making aspect is crucial in programming, enabling the creation of dynamic and responsive applications.

For instance, a common use of conditional statements is seen in "if" statements, where a particular block of code runs only if a defined condition is met. Additionally, "else" and "else if" constructs can be used to specify alternative actions based on different conditions, enhancing the logic flow of the program.

In contrast, iterative statements are designed for repeating a section of code multiple times until a certain condition is met, sequential statements execute code in a linear fashion without making decisions, and control loops are a broader term that often encompasses iterative statements. However, they do not specifically address the concept of decision-making, which is central to conditional statements. Therefore, conditional statements are the fundamental construct used in programming for making decisions.
