Assertion (A): At low temperature (say \( 0^{\circ} \mathrm{C} \) ) the effect of attractive forces dominates for \( \mathrm{CO}_{2}, \mathrm{CH}_{4} \) and \( \mathrm{N}_{2} \), whereas the molecular size effect dominates for \( \mathrm{H}_{2} \) and \( \mathrm{He} \) to explain deviations.
Reason (R): \( \mathrm{Z}1 \) for \( \mathrm{H}_{2} \) and \( \mathrm{He} \), whereas \( \mathrm{Z}1 \) for \( \mathrm{CO}_{2}, \mathrm{CH}_{4} \) and \( \mathrm{N}_{2} \).
(A) Both A and R are true and R is the correct explanation of A.br(B) Both A and R are true, but R is not the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(E) Both A and R are false.
