A Correct answer
Explanation

Diagonal relationships exist between elements diagonally adjacent in the periodic table: Li-Mg (1st period, 1st group to 2nd period, 2nd group), Be-Al (2nd period, 2nd group to 3rd period, 3rd group), and B-Si (2nd period, 3rd group to 3rd period, 4th group). Li-Be are in the same period and do NOT show diagonal relationship.
