The right option is; at a transform boundary
Shearing often occur at a transform boundary. A transform boundary is a place where two of the tectonic plates slide sideways past each other. Shearing is the lateral distinct motion of two rock surfaces against each other. The motion is usually caused by intense pressure under the earth’s crust and it affects the rocks, making their shapes to change as they slide against each other.
The correct answer is C.at a transform boundary
This is because shearing is caused when two plates tectonics move apart from each other which is called transform boundary
Hope this helps :)
