JEE Main 2024 Chemistry question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): NH and NF molecule have pyramidal shape with a lone pair of electrons on nitrogen atom. The resultant dipole moment of NH is greater than that of NF. Reason (R): In NH, the orbital dipole due to lone pair is in the same direction as the resultant dipole moment of the N–H bonds. F is the most electronegative element. In the light of the above statements, choose the correct answer from the options given below:

• (A)Both (A) and (R) are true and (R) is the correct explanation of (A)Correct
• (B)(A) is false but (R) is true
• (C)(A) is true but (R) is false
• (D)Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
