The correct answer is D. Two 45 minute period with a reset at half time.
A football match consists of two 45-minute halves, with a 15-minute break between them. The clock is stopped for injuries, substitutions, and other stoppages, so the actual playing time is usually less than 90 minutes. The team with the most goals at the end of the match wins. If the score is tied at the end of regulation time, there is usually extra time (two 15-minute periods) and, if necessary, a penalty shootout to determine the winner.
Option A is incorrect because a football match consists of two 45-minute halves, not two 15-minute halves.
Option B is incorrect because a football match consists of two 45-minute halves, not two 25-minute halves.
Option C is incorrect because a football match consists of two 45-minute halves, not two 35-minute halves.
