D Correct answer
Explanation

The sequence follows a pattern where each term is multiplied by 1/3 to get the next term. Starting with 9, 9 * 1/3 = 3, 3 * 1/3 = 1, 1 * 1/3 = 1/3, and 1/3 * 1/3 = 1/9.

AI explanation

The series is created by dividing the previous term by 3. Dividing 9 by 3 gives 3, dividing 3 by 3 gives 1, dividing 1 by 3 gives 1/3, and dividing 1/3 by 3 gives 1/9. The missing number is 1.
