c) hold a light to it and examine its luster
d) examine it’s streak color

The answer is A

If this a multiple answer question the answers would be A and B

 Option B

Explanation: The classification of rocks is done by studying about the texture, color and layers.

The texture of the rock can be defined as the minerals grains that constitute to form a rock. The grain vary in size and shape.
