  • A Abdominal muscles
  • B External intercostal muscles
  • C Diaphragm
  • D Internal intercostal muscles
Correct Answer: Option A

Explanation

The process of breathing involves the contraction and relaxation of various muscles, including the diaphragm, external and internal intercostal muscles, and abdominal muscles. During normal breathing, the diaphragm and external intercostal muscles are primarily responsible for inspiration, while expiration is mostly passive. However, when greater force is required for inspiration and expiration, the abdominal muscles can be recruited to increase the strength of breathing. This type of breathing is sometimes called forceful breathing and is often seen in pregnant women, individuals with respiratory muscle weakness, and during certain physical activities such as singing or playing wind instruments.
