Its C because the the amount of carbon dioxide produced or oxygen used does not depend on the surface area. However, the no of hormones detected are on cell surface membrane and thus its affected by surface area
True

Hormones are detected by the receptors on membrane of the cell. So the greater the cell surface area, the bigger the number of receptors that can detect hormones. The amount of gases used/produced in respiration are dependent on cell volume, as the bigger the cell the more consumption/production
