Explanation:

- In the set (55, 11, 25), dividing 55 by 11 gives 5, and multiplying 5 by 5 gives 25.

- In the set (64, 16, 16), dividing 64 by 16 gives 4, and multiplying 4 by 4 gives 16.

- Both sets follow a pattern: Divide the first number by the second, and then square the result to get the third number.

- Option 1: In (33, 11, 9), dividing 33 by 11 gives 3, and squaring 3 gives 9.

- Option 2: In (33, 11, 22), dividing 33 by 11 gives 3, and squaring 3 gives 9, not 22.

- Option 3: In (33, 11, 3), dividing 33 by 11 gives 3, but squaring 3 gives 9, not 3.

- Option 4: In (33, 11, 10), dividing 33 by 11 gives 3, but squaring 3 gives 9, not 10.

Option 1 is correct: (33, 11, 9) follows the same pattern.
