Final answer:
The statement is true; the condition that dictates the continuation of a loop is called the loop control expression. It is evaluated before each iteration and determines when the loop ends.
Step-by-step explanation:
The condition that determines whether iteration is to continue in a loop is indeed known as the loop control expression. This statement is true (a). The loop control expression is evaluated before each iteration, and as long as it evaluates to true, the loop will continue to execute its block of code. When the expression evaluates to false, the loop will terminate.
