Option C (very coarse texture) is the appropriate one.
Explanation:
Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively.
We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.
Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
I think it's the first one: the red fox that inhabits farmlands and forests has a red coat, but it's relative, the kit fox, lives in a desert has a sandy-colored coat
