Assertion and Reason Analysis:
Assertion: Forceful expiration occurs through expiratory muscles.
Reason: Expiratory muscles expire quickly.

Explanation:

Assertion is true:
- Forceful expiration indeed occurs through the contraction of expiratory muscles, which help in pushing air out of the lungs with more force than during normal breathing.

Reason is false:
- The reason given, that expiratory muscles "expire quickly," is incorrect. The term "expire" does not apply to muscles in this context. The expiratory muscles contract to facilitate expiration, not expire themselves.
Therefore, the correct answer is option 'C', where the Assertion is true but the Reason is false. The expiratory muscles do not "expire quickly," but they contract quickly and forcefully to aid in forceful expiration.

In forceful expiration requiring effort, a different group of intercostal and some abdominal muscles contract to reduce the volume of thorax more than that in ordinary respiration. So, a larger volume of air is breathed out, such muscles are called expiratory muscles.
