Answer and explanation
Correct answer: [3, 4]
For an interval to be a subset of [2, 5], every number in that interval must lie between 2 and 5, including the relevant endpoints. Every number in [3, 4] is also in [2, 5], so [3, 4] is a subset. The other intervals contain numbers below 2 or above 5, so they cannot be subsets.
