Right answer is (c) Net and Gross primary productivity
 
Explanation: Gross primary productivity and net primary productivity are the two types of primary productivity. The rate of production of organic matter during photosynthesis is defined as the gross primary productivity, while the net primary productivity is the energy left after the respiration i.e. the gross primary productivity subtracted by respiration losses.
