NEET 2024 Chemistry question on Hydrocarbons

Given below are two statements.

Statement I: The boiling point of three isomeric pentanes follows the order ntext−pentane>textisopentane>textneopentanen\\text{-pentane} > \\text{isopentane} > \\text{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:
  1. A.
    Statement I is correct but Statement II is incorrect
  2. B.
    Statement I is incorrect but Statement II is correct
  3. C.
    Both Statement I and Statement II are correct
  4. D.
