(D) The temperature coefficient $(Q_{10})$ is defined as the ratio of the rate of a reaction at a temperature $T + 10^{\circ}C$ to the rate of the reaction at temperature $T$.For most biological processes,including photosynthesis,the $Q_{10}$ value is approximately $2$ within the physiological temperature range.This means that for every $10^{\circ}C$ rise in temperature,the rate of photosynthesis approximately doubles,provided other factors are not limiting.
