Solution

The correct option is A Monocondylic
A) Birds have only one occipital condyle (monocondylic) and so can rotate their heads up to 270 degrees.
B) Mammals and amphibians are dicondylic.
C) Amphicondylic means skulls can be either monocondylic or dicondylic.

So, the correct answer is option A.
