Q: The statement to stop the execution of a construct

Answer: B

Explanation:

To stop the execution of a construct, such as a loop or a switch statement, the correct statement is:

b) break

break: This statement is used to exit from a loop (like for, while, or do-while) or a switch statement. When break is encountered, the execution of the loop or switch construct is immediately terminated.
System.exit(0): This terminates the entire Java Virtual Machine (JVM), not just a single construct.
stop: This is not a valid Java statement for stopping execution.
end: This is not a valid Java statement for stopping execution.
