Answer 1

Answer: (C)

Concentration of salts is very high in the soil

A physiologically dry soil is a soil in which the concentration of oxygen is very less and that of salt is very high. Normal plants cannot grow in such soil and only halophytes are found in them. The Sunderbans in West Bengal are rich in physiologically dry soil. Thus the correct answer is option C.
