The primary muscle used in active expiration is the diaphragm (it
relaxes from its contracted state to decrease the volume in the lungs, forcing air out).
Internal intercostals, the interosseous portion, will assist by pulling the rib cage down.

Is expiration during respiration passive or active and what muscles are used?
It can be entirely passive, since the lungs expel air as they deflate. However, voluntarily breathing out forcefully is part of some exercises, using the abdominal muscles to push the diaphragm upward.
What muscle is contracted to exhale forcibly?
Diaphragm & interna intercostal muscle
Which muscies is responsible for inspiration when breathing?
The diaphragm, a sheet of muscles spanning the rib cage just below the lungs, is mainly responsible for both inspiration and expiration. The intercostal muscles are also used, expanding and contracting the the space between the ribs. The abdominal muscles are used to a lesser extent either by relaxing to allow further expansion of the diaphragm or contraction for rapid expulsion of air. (Note to the person who answered this question previously: "Inspiration" means to inhale. "Expiration means to exhale. Don't tell someone that they don't know what they are talking about unless you know what you are talking about.)
