The texture of a rock is determined by 3 components of the grain: size, shape and pattern.
The rock in your image (although not very clear in your picture) seems to have very large grains as opposed to several coarse grains. Furthermore, the pattern on the rock is uniformly colored and non-banded.
Thus, from what I can discern in the image, the statements that best describe the rock would be:
The grains in this rock are very large and
The rock has a non-banded pattern.
