Answer and explanation
Correct answer: A={5,6,7,8,9,10,11}
In this context, between 4 and 12 means greater than 4 and less than 12, so neither endpoint is included. The natural numbers satisfying both conditions are 5, 6, 7, 8, 9, 10, and 11. Options A, C, and D incorrectly include one or both endpoints. Thus option B is correct.
