Explanation:

Alright, let's break it down step by step.

- Look at the pairs:

- 3462 ? 2250

- 4424 ? 3212

- 2424 ? ?

- What’s happening? Check each digit for a pattern.

- In 3462 and 2250, each digit is reduced by 1:

- 3 ? 2

- 4 ? 2

- 6 ? 5

- 2 ? 0

- Same in 4424 ? 3212:

- 4 ? 3

- 4 ? 2

- 2 ? 1

- 4 ? 2

- So, it’s a simple rule: subtract 1 from every digit.

- Now, apply it to 2424:

- 2 ? 1

- 4 ? 3

- 2 ? 1

- 4 ? 3

- That gives us 1313.

- But 1313 isn't one of the options. Let's double-check if maybe the rule is different.

- Try dividing each digit by 2:

- 3462 ? 2250:

- 3/1.5 ? 2

- 4/2 ? 2

- 6/3 ? 5

- 2/1 ? 0

- That doesn't fit either.

- Check for a mirrored pattern:

- 3462 ? 2250:

- 3+2=5 ? not matching

- Or, could the number be halved? Doesn't match.

- 4424 ? 3212

- 4-1=3

- 4-2=2

- 2-1=1

- 4-2=2

- Pattern: (first digit minus 1), (second minus 2), (third minus 1), (fourth minus 2)

- Apply that to 2424:

- 2-1=1

- 4-2=2

- 2-1=1

- 4-2=2

- That gives us 1212.

- So, option 3: 1212 is absolutely right.

- The options:

- 2211: Pattern doesn’t fit

- 1122: Same

- 1212: This fits the discovered subtraction pattern

- 1221: No match

The correct answer is Option 3: 1212.
