I think it's B) Iliopsoas. It's the main hip flexor.

Vastus lateralis sounds familiar, but I’m pretty sure it’s not the right one for hip flexion.

I’m torn between the iliopsoas and the gluteus maximus. I feel like I need to double-check my notes.

I remember practicing a question like this, and I think the iliopsoas was definitely the answer.

I think the iliopsoas is the main muscle for hip flexion, but I’m not completely sure.
