Correct answer: A.) An underground water source

The sub-irrigation is the method of watering plants from the below instead of above the ground. It is also known as seepage irrigation. In this method of irrigation water is sprayed directly to the plant root zone directly and it is directly taken up by the roots to the plants. It is an environmentally responsible alternative method that conserves water and fertilizers.

Hence, the correct answer would be option A.
