Nailed it! The diaphragm is the boss of inhalation. Though I'd love to see someone try to breathe with their pecs.

The diaphragm, easy peasy. Although I do wonder if the abdominals play a role in forced exhalation. Hmm, maybe I should review my respiratory muscle anatomy.

Haha, I bet the pectoralis major was a trick answer. As if our pecs could power our breathing! Gotta go with the diaphragm on this one.

Oof, this one's a tricky one. I'm torn between the diaphragm and the intercostals, but I think the diaphragm takes the cake.

The diaphragm is the correct answer here. It's the main muscle responsible for initiating inhalation.

I'm not sure, but I think it's either A) Intercostals or C) Diaphragm.
