It is made up of two bones that are clavicle and the scapula.
00:26
The pelvic griddle is made up of three bones which are ilium, ischium and humus.
00:56
The pelvic bones are bones are fused together to form a basin shaped structure that is much stronger and more massive than pectoral girdle.
01:43
This is because of the pelvic girdle needs to support the weight of the upper body and transmit it to the lower limbs.
02:22
So according to the discussion the correct answer is the pelvic girdle is comprised of two massive bones which are adapted for weight bearing.

So, this is the correct answer for this question.
03:21
This is the option b.
03:25
And let's see why the other options are incorrect.
03:29
Because the pelvic griddle does not articulate with axial skeleton.
03:51
When the pelvic griddle articulates with sacrum which is a part of axial skeleton and the next option is the pelvic griddle is part of the axial skeleton because the pelvic griddle is part of appendicular skeleton which includes bones of the limbs...
