Answer: A

Explanation:

In the provided pseudo-code for the Bingo program, the variable MIN is used in the statement MIN = MIN + A without being initialized with a value beforehand. This represents a classic ‘use before define’ anomaly, as the variable MIN must have an initial value before any operation like addition can be performed on it.
