d. focus

Explanation:

The point beneath the Earth’s surface where the rock breaks under stress and triggers an earthquake is called the focus. This point is also called hypocentre. The focus is located deep underground at the boundary of a tectonic plate where the plate boundary begins to rupture and causes an earthquake. The point just above the focus on the Earth surface is called epicentre.  

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
