I bet the person who wrote this question has a really 'muscular' sense of humor. Puns and all.

C) Quadratus lumborum and cervical erector spinae, no doubt. That's the only option that makes sense for phasic muscles.

I think the other options are more related to tonic muscles.

I agree, Quadratus lumborum and cervical erector spinae are definitely phasic muscles.

Hmm, this one's tricky. I'm leaning towards D) Gastrocnemius and soleus, but I could be totally off. I guess I need to brush up on my muscle groupings.

B) Temporalis and masseter? Really? Those are postural muscles, not phasic. I'm pretty sure the answer is C.

I'm not sure, but I think C) Quadratus lumborum, cervical erector spinae are also phasic muscles because they are used for stabilization.

I think the correct answer is C) Quadratus lumborum, cervical erector spinae. Phasic muscles are typically involved in dynamic movements, and those muscle groups fit the bill.
