A. C with a underscore and line through it

B. C

C. E

D. C with an underscore

Answer 1

the set on the left is a superset of the one on the right. The superset symbol looks rather like a backwards "C", while the subset symbol looks like a forwards "C". Of the options listed, the correct relationship is "not a subset of", which would be a forwards "C" with a line through it. That's option A.
