this question is from a korean book IQ festival practical mensa IQ test and book has no answer.
I'm pretty sure the answer is
Different from GileBrt's answer, Imagine each column representing 3 three-dimensional jars
The first row will give a point of view if we look from above (from the mouth of the jar), the dark part is the inside of the jars
The second row will give a point of view if we look from the side
The third row, I think it should give a point of view if we look from the bottom, so the answer is D
I think the answer is
The third row reflects the area colored in the first row.
