Correct Answer

Explanation

In addition to the respiratory muscles such as diaphragm and external intercostal muscles, the abdominal muscles can help in increasing the strength of breathing. During forceful breathing, the abdominal muscles contract to help increase the intra-abdominal pressure, which in turn pushes the diaphragm upwards and helps in forceful expiration. This can be observed in activities such as coughing, sneezing, and laughing. Hence, option C is the correct answer.
