Answer:
Option A
Explanation:
If a football team gains 15 yards on a play, it will be recorded as '+ 15' or '15'.
All other options would be represented by '-15', and not '15' that is asked in the question. A withdraw is taking away money, a number 'below zero' would be negative, and losing 15 points would be represented as '-15'.
Option A should be the correct answer.
