76. How can we explain the fact that CCl₄ is a liquid and CL. is a solid at 25℃? Which of the following options is the best explanation?
(A) CCl₄ has a larger dipole moment than Cl₄ due to the higher electronegativity of CI compared to I.
(B) Cl₄ has a larger dipole moment than CCl₄ because there is stronger electron repulsion in the Cl-I bonds than in the C-CI bonds.
(C) London dispersion forces are stronger in C Cl₄ than in  Cl₄ because Cl is more electronegative than I.
(D) London dispersion forces are stronger in  Cl₄ than in C Cl₄ because  Cl₄ has a more easily polarizable electron cloud.
(E) None of the above.
