Correct answer: 2

The interval [2, 5] is a closed interval because square brackets are used at both ends. This means that every real number from 2 through 5 is included, including both endpoints 2 and 5. Among the choices, 2 is included, whereas 1, 6, and 5.5 lie outside the interval. Thus option A is correct.
