If I={2,3,4}, which option is a subset of I?
Answer and explanation
Correct answer: {2,4}
The governing concept is the subset condition: every element of a proposed subset must belong to the original set. Both 2 and 4 are elements of I={2,3,4}, so {2,4} is a subset and option A is correct. Option B contains 5, C contains 1, and D contains 5; none of those outside elements belongs to I, so those options are not subsets.
