Final answer:
The statement is true because in an else-if construct, only the code block associated with the first true condition is executed and then the construct is exited.
Step-by-step explanation:
The statement "Only the statements associated with the first true condition are executed in a multiway else-if construct." is true. In programming, when using an else-if construct, the code checks each condition in turn until it finds one that is true. Once it finds a true condition, it executes the block of code associated with that condition and then exits the else-if construct without checking any remaining conditions.
