Question $1$

Suppose the main function has no exception handlers and calls function $A.$ Function A has exception handlers for exceptions of type $x$ and $Y,$ and it calls function $B.$ Function $B$ has no exception handlers. If function $B$ throws an exception of type $Z,$ what happens?

Control exits function B immediately and transfers to an exception handler in function $A.$

The rest of the code in function B completes its execution, and then control transfers to an exception handler in function $A.$

Control exits function B immediately and transfers to the main function.

The program terminates immediately with an error message.
