Read the following statements.

Statement I: Only first seven pairs of ribs (true ribs) are bicephalic in nature.

Statement II: A rib is considered bicephalic, when it has two articulation surfaces on its dorsal end.

In the light of given statements, choose the correct answer from the options given below.

There are 12 pairs of ribs. Typically, the ribs are attached dorsally to vertebral column by two articulation surfaces are so are bicephalic (the floating ribs are monocephalic).

True ribs articulate with sternum directly on the ventral side.

False ribs articulate with sternum indirectly (to the 7^th rib).

Floating ribs do not articulate ventrally to any other rib or sternum.
