Question

Evaluate the following statements related to group 14 elements for their correctness. (A) Covalent radius decreases down the group from $C$ to $Pb$ in a regular manner. (B) Electronegativity decreases from $C$ to $Pb$ down the group gradually. (C) Maximum covalance of $C$ is 4 whereas other elements can expand their covalance due to presence of d orbitals. (D) Heavier elements do not form $p π - p π$ bonds. (E) Carbon can exhibit negative oxidation states. Choose the correct answer from the options given below :
