The pka of alpha amino group is 9 and pka of carboxyl group is 2. The answer is D.

It should be (A). As their PKA values lie between 1.03 - 12.1.

This answer is inaccurate. Typically the C terminus has a pka around 3 and the N terminus has a pka around 8. Although these are not exact numbers these are the relative values used.
