Explanation:

Alright, here’s what’s really happening:

- Let’s look for a pattern:

- 2 = 0. The difference is 2.

- 5 = 1. The difference is 4.

- 8 = 4. The difference is 4.

- Actually, try this: all results are the remainder after dividing by 4.

- 2 mod 4 = 2 ? But you have 0, so maybe it’s something else.

- 5 mod 4 = 1

- 8 mod 4 = 0 ? You have 4, not 0...

- Let’s check digit sum:

- 2: digits sum to 2. Output is 0.

- 5: digit sum 5. Output 1.

- 8: sum 8. Output 4.

- Another try: halve the number and round down:

- 2/2 = 1, but answer is 0.

- 5/2 = 2.5 ? 2, answer is 1.

- 8/2 = 4, answer matches 4.

- Now for 11:

- 11/2 = 5.5 ? 5.

- Compare to options:

- 1: 8

- 2: 9

- 3: 10

- 4: 6

- None match so far. Let’s check another angle: numbers increasing by 3, 3, 3...

- 2 (0), 5 (1), 8 (4) — the output jumps by 1, 3.

- Try (number - previous number) = (output - previous output):

- 2?5: +3, 0?1: +1

- 5?8: +3, 1?4: +3

Weird, let’s look for another pattern. Check if it’s squaring the digits or something similar.

- Actually, what if output = (number - 2)^2 / 3?

- 2: (2-2)^2/3 = 0

- 5: (5-2)^2/3 = 9/3=3, but answer is 1...

- One more: 2?0, 5?1, 8?4. The output seems unrelated.

Wait:

Maybe the answer is just the next odd number after the previous answer:

* 0 (for 2)

* 1 (for 5)

* 4 (for 8)

* Next: +5 ? Should be 9.

So, 11 = 9.

Options:

- 1: 8

- 2: 9

- 3: 10

- 4: 6

Green tick for 9.
