Definition of aniline point. : the lowest temperature at which aniline and a solvent (as gasoline) are completely miscible and which serves as an indication of the type of hydrocarbons present in the solvent, the content of aromatics being higher according to as the temperature is lower.

So as per definition the should be A.

A is the right answer.

The aniline point of an oil is defined as the minimum temperature at which equal volumes of aniline (C6H5NH2) and the lubricant oil are miscible, i.e. form a single phase upon mixing.

The value gives an approximation for the content of aromatic compounds in the oil since the miscibility of aniline, which is also an aromatic compound suggests the presence of similar (i.e. aromatic) compounds in the oil. The lower the aniline point, the greater is the content of aromatic compounds in the oil.
