IMO C

from statement 1
only the amount of alcohol is known.
TOTAL amount of mixture is not known
Hence insufficient.

From statement 2
only the amount of oil is known.
Same story as Statement 1
Insufficient.

Combining
ratio of oil= 40/100
Hence C

As without the information that the solution comprises only two things viz alcohol and oil we can't assume it.
