If a, b, and c are prime, is abc odd?
(1) a = 3
(2) c = 2
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT SUFFICIENT

As a, b and c are prime and only even prime is 2, abc will be odd only when none of these three is 2.
(1) a = 3
If any of b or c is 2, then no, otherwise yes.
Insufficient
(2) c = 2
Irrespective of value of a and b, abc will always be even.
Sufficient
