Assertion : PF(3) is stronger lewis base...

Assertion : `PF_(3)` is stronger lewis base than `PH_(3)`.
Reason : l.p. of P-atom in `PF_(3)` molecule is present in `sp^(3)`-hybrid orbital, whereas l.p. of P-atom in `PH_(3)` is present in almost pure s-orbital.

A

If assertion is true but the reason is false

If assertion is false but reason is true

C

If both assertion and reason are true and the reason is the correct explanation of assertion

D

If both assertion and reason are true and the reason is not the correct explanation of assertion
