(B). Increasing the number of layers in the chloroplasts of plant changes would lead to an increase in surface-area-to-volume ratios.
A surface-to-volume ratio compares an object's surface to its interior volume. The surface and volume are inversely related. The surface-to-volume ratio decreases with increasing object size and vice versa.
Surface area (S)
S= Length*Height*the number of sides
Volume (V) = Length*Width*heigh
Surface: Volume area = S/V
The sponge's surface would be reduced if its choanocyte projections on the outside of the body were reduced, which would result in an increase in the surface-to-volume ratio. The surface of the chloroplasts would expand and the surface-to-volume ratio would drop as the number of layers in the chloroplasts of plants increased.
