Evaluate the following statements related to group $\displaystyle 14$ 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 $\displaystyle 4$ whereas other elements can expand their covalance due to presence of d orbitals.
(D)
Heavier elements do not form $\displaystyle \mathrm{p} \pi-\mathrm{p} \pi$ bonds.
(E)
Carbon can exhibit negative oxidation states.
