Answer : The best pressure is 110 GPa of the lower mantle.

Explanation : We know that the pressure in the lower mantle starts at 24 GPa and reach a 136 GPa at the boundary.

So, the best pressure is 110 GPa because 220 GPa, a 305 GPa and 360 GPa are the higher value of  the maximum value 136 GPa of the lower mantle.

Answer:

(A) 110 GPa
