If P to T are second period p-block elements then which of the following graph show correct relation between valence electrons in P2 to T2 (corresponding molecules) and their bond order is :

Correct answer: A. Step 1: Map the diatomic molecules of second-period p-block elements: B2 (6 valence electrons, BO = 1.0), C2 (8 valence electrons, BO = 2.0), N2 (10 valence electrons, BO = 3.0), O2 (12 valence electrons, BO = 2.0), and F2 (14 valence electrons, BO = 1.0). Step 2: Plotting these values on a coordinate system with Valence Electrons on the x-axis and Bond Order on the y-axis yields a symmetrical triangular peak shape. Step 3: Graph (d) correctly illustrates this peak, maximizing at 10 valence electrons with a bond order of 3.0, and going down to 1.0 at 6 and 14 valence electrons.
