Now i understand this question,

A low melting point doesnt mean its impure...

ice can have a lower melting point compared to other substances,

If the option said, it has a lower melting point than the actual pure substance, then we would have said that C is correct.

Option C is vague, its not direct.

Option A is the appropriate Answer
