$ C \cap D $ means the set that contains all members of C which are also present in D.
Since D={2,4,6,8,10,12,14,16,18,20}
can you find $ C \cap D $?

The intersection of two sets is a set containing all elements present in both sets.
You already have set C written out. Now think of what numbers are in set D. Then figure out which ones are in both sets.
