Correct answer: C. Unit C
Worked solution
- Unit A: 500 → 550, a rise.
- Unit B: 400 → 450, a rise.
- Unit C: 600 → 450, a fall.
Answer: Unit C.
The idea
Compare the two rows one column at a time. Only one column needs to fall for the answer to be that unit.
Shortcut. Units A and B climb by exactly 50 every month, so only C, the irregular column, can fall — and 600 → 450 does.
Common trap. "None of them" — assuming the steady monthly rises of Units A and B hold for every column; C falls from 600 to 450.
