The pictures below represent three soil profiles. Three images shown in a row, showing various soil profiles. Profile A (the one on the far left) shows plants at the top with one fairly uniform layer of larger rocks beneath. Profile B (in the middle) shows plants at the top with three distinct layers. The top layer is very granular, the middle layer is medium sized rocks and the bottom layer is larger rocks. Profile C (the one on the far right) shows plants growing on top of two distinct layers. The top layer is very granular and the lower level is made up of large rocks.

Which of these statements is correct about the soil profiles?

Profile A has more clay than Profile B and Profile C.
Profile B has more clay than Profile A and Profile C.
Profile A and Profile B have the same percent of clay.
Profile B and Profile C have the same percent of clay.
