Which of the following changes in a rock during physical weathering

A SIZE AND SHAPE
B COLOR
C LUSTER
D MINERAL COMPOSITION

Physical weathering involves simply making little rocks out of big rocks. The answer should be "A". It is unfortunate that whoever made up the question included mineral physical properties (choices B C and D) to offer as answers. It indicates a poor understanding of the difference between rocks and minerals. (I hope you did not make up the question and answers.)

This question is too general, because all the depends on the composition of the rock, which makes all of the above possible, but, (A) would be the most general

Easy! A!!!
