(B) The range is always a subset of the codomain
(C) The codomain is always a subset of the range

Show Answer
Answer: B
Explanation:
(A) Incorrect. The codomain can be larger than the range.
(B) Correct. The range is always a subset of the codomain. The codomain includes all possible output values, while the range only includes the actual output values.
(C) Incorrect. The codomain can be larger than the range, not a subset of it.
(D) Incorrect. The range is a subset of the codomain, so they cannot be disjoint.
