Option C

St1: x=6(m+3) where m is the quotient. But no info about y. Clearly insufficient

St2: y=6(n+1) where n is the quotient. No info about c. Insufficient

Combining,
x+y= 6(m+n+4)/6
Hence remainder will be 4. Sufficient

Answer = C
St1: No info about y , hence insufficient.
St2: No info about x, hence insufficient.
Combing St1 & St2
we get to know that remainder is 3+1 = 4.
hence sufficient.
