Question

Given below are two statements: \ Statement I : The boiling point of three isomeric pentanes follows the order : $n$-pentane > isopentane > neopentane. \ Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point. \ In the light of the above statements, choose the most appropriate answer from the options given below :
