Which of the following are examples of control structures?

Control structures are essential programming constructs that dictate the flow of execution within a program based on certain conditions or iterations. The correct choice includes valid examples of common control structures used in programming.

The inclusion of "if," "if/else," "while," and "for" in the selected option showcases a variety of control structures that manage conditions and loops. The "if" statement allows the program to execute certain code if a specified condition is true, while the "if/else" structure provides an alternative path for execution if that condition is false. The "while" loop is capable of repeating a block of code as long as a specified condition holds true, allowing for dynamic control over iterations. The "for" loop, in contrast, is used for executing a block of code a specific number of times, providing another way to handle repetitive tasks.

This versatility in handling flow control is what makes the selection a well-rounded set of control structures. The other options include structures that might not capture the same breadth and depth of control mechanisms or incorporate names that are less conventional in describing standard programming practices.

Thus, the selected answer effectively represents a diverse and cohesive set of control structures commonly found in many programming languages.
