Directions: Identify the correct idiom or phrase to complete the sentence.

When I came back home late at night, my father__________.

The correct answer is A because 'blew his top' is a common idiom meaning to lose one's temper or become extremely angry. In the context of coming home late at night, this is the appropriate expression for a parent's angry reaction. The other options ('blew his hat', 'blew his anger', 'blew his back') are not standard English idioms.
