Solution

The correct option is B Both Assertion and Reason is true and Reason is NOT the correct explanation of Assertion
Assertion : The $N H_{3}$ molecule is more polar compared to $N F_{3}$ molecule.

The electronegativity difference between N and H is greater than the electronegativity difference between N and F.

Reason: Fluorine atoms are larger compare to hydrogen atoms and fluorine atoms have the additional shell of electrons.

Thus, both statements are correct but the reason is not the correct explanation of Assertion.
