Question

When comparing control flow structures, it's helpful to focus on how they use conditions to decide what happens next.
Option 1: 'logical AND statement' — This is not a control structure like a loop or a conditional; it's a boolean operator used inside conditions to require multiple true subconditions. While a while loop might use a condition that incorporates AND, that does not make the loop itself similar to an AND statement.
Option 2: 'else statement' — An else branch is part of an if/else pair and represents what happens when a condition is false. A while loop does not have an else branch by default and its behavior isn’t defined by choosing between two branches based on a single evaluation; it repeatedly tests a condition and loops, which is distinct from an if/else structure.
Option 3: 'if statement' — This option points to a single-evaluation conditional that determines whether a block of code runs. A while loop also relies on a condition to decide whether to execute its block, but it repeats the block as long as the condition remains true. In that sense, the mechanism of deciding whether to enter or continue looping is analogous to an if statement, though the repetition makes the behavior different.
Option 4: 'logical NOT statement' — The NOT operator negates a boolean expression, changing true to false and vice versa. It’s a logical modifier, not a control structure like a loop or conditional, so this is not analogous to a while loop.
Overall, the most fitting analogy among the options is the if statement, because both use a condition to determine whether a block of code should run (though a while loop repeats the block). The other options describe distinct constructs or operators that do not capture the looping decision mechanism of a while loop.
