D Correct answer
Explanation

This is the correct option as all statements are correct regarding irrigation. Irrigation provides sufficient moisture for the germination of seeds as seeds do not germinate in dry soil. Irrigation is also essential for the growth and elongation of the roots. This is because the roots of the crops fail to develop in dry soil. But, statement 'a' is also correct. Thus, it is a wrong option.
