The Correct Option is A

Solution and Explanation

Explanation:
Given compounds are:
We have to find the compound which has the lowest melting point .We know that, greater the intermolecular forces of attractions, greater is the melting point of the substance. Polarity is directly proportional to intermolecular forces of attraction. Non-polar compounds have weak van der Waals' forces of attraction. Naphthalene (compound A) is a non-polar compound thus, it will have lowest melting point. All other three compounds are polar having
present in them which are polar groupsHence, the correct option is (A).
