Answer:
The rock on the right is foliated
Explanation:
There are three types of rocks. Metamorphic, igneus and sedimentary.
Igneus rocks are formed from magma that cooled in one point of earth history, so non of the metamorphic rocks is formed from cooled magma.
Sedimentary rocks are formed from varios sediments or grains that after processes of pression or temperature compact together. So, metamorphic rocks are not formed from randomly arranged grains
Metamorphic rocks are rocks that change their shape for a phisical reason. One common way to find metamorphic rocks is foliated, this means that the rock has layers. Like a book, with different sheets.
When a metamorphic rock is formed from granite, the pattern is foliated, with layers and the form of the rock is usually banded, this rock is called Gneiss. The left image is not layered.
The right image is layered like sheets, this is the only option that has no counter arguments
