wrong (b) and (c)
 
(b) The rate of photosynthesis decreases in no rainfall area as water is one of the main raw material needed by plants for photosynthesis. Water also brings other nutrients along with it. If there is no rainfall in an area, there will be less water available to plants resulting in the decrease of photosynthesis process.

(c) The rate of photosynthesis will increase because plants need raw minerals such as N, P, Fe, Mg etc., for performing the various functions as well as for their growth. They take these minerals from the soil along with the water in dissolved form so Good manuring in the area increase the amount of these minerals in the soil and also help them to provide micro as well as macro nutrients thus, increasing the rate of photosynthesis.
