D Correct answer
Explanation

Statement 1 gives a relationship (chairs = 2 × stools) but no actual count. Statement 2 gives the count of stools (12) but no relationship to chairs. Neither alone can answer the question. Together, we can calculate: chairs = 2 × 12 = 24. Both statements are necessary and sufficient.
