​Which of the following pairs of elements belonging to the same group exhibit similar chemical properties?​

Correct option is D

The correct answer is (D) N and P.

• Group 15 (Nitrogen Group): Nitrogen (N) and Phosphorus (P) both belong to Group 15 of the periodic table.  
• Similar Chemical Properties: Elements in the same group have the same number of valence electrons (electrons in the outermost shell). This similarity in electronic configuration leads to similar chemical properties.
