Explanation:

Let's examine the relationships between the numbers:

- In the set (12, 40, 14):

- Start with 12.

- Multiply by 3 to get 36.

- Add 4 to reach 40.

- Subtract 26 to arrive at 14.

- In the set (15, 33, 9):

- Start with 15.

- Multiply by 3 to get 45.

- Subtract 12 to reach 33.

- Subtract 24 to arrive at 9.

Now, let's evaluate the options:

1. Option 1 (11, 105, 42):

- Start with 11.

- Multiply by 3 to get 33.

- Addition does not match to 105; the set does not fit.

2. Option 2 (21, 35, 41):

- Start with 21.

- Multiply by 1.67 to reach close to 35, doesn't match the pattern correctly.

3. Option 3 (21, 95, 35):

- Start with 21.

- Multiply by some factor and adjustments; numbers don't fit the exact pattern.

4. Option 4 (21, 91, 35):

- Start with 21.

- Multiply by 3 to get 63.

- Add 28 to get 91.

- Subtract 56 to arrive at 35.

Thus, the option where the numbers align with the same operational structure is:

- Option 4 (21, 91, 35)
