Explanation:

Question 46

The lower leg has two bones: tibia (larger, medial) and fibula (smaller, lateral). Femur is a thigh bone, patella is the kneecap. So the smaller, lateral lower leg bone is fibula.

Axial skeleton includes skull, vertebral column, rib cage. Vertebra is part of the vertebral column (axial). Tarsal (foot), femur (thigh), clavicle (shoulder girdle, appendicular) are in appendicular skeleton.

Spongy bone has trabeculae (needle - like structures) with open spaces. Compact bone is dense/solid. Spongy bone isn't gel - like or as dense/compact as compact bone. So the first option describes spongy bone.

Answer:

B. fibula (assuming the second option is fibula; if options are labeled as per the image, e.g., if the second option is "fibula", then the answer is the option with "fibula")
