Yield of well is the rate at which water percolates into the well under the safe maximum working head or critical depression head. It is expressed in m3/hr or It/min. The yield of open well can be determined by any one of the two methods, namely, pumping test and recuperation test.

@All.
Option A should be the answer.
Option B represents the discharge.
Option C Represents water available in the well means porosity.
Option D represents Specific capacity.

Absolutely correct. @Utkarsh.
The specific field is defined as the volume of water that can be drained under gravity per unit volume of the aquifer.

The question asks specific yield of the well (& not aquifer).
Specific yield of AQUIFER = Ratio of water yielded under gravity & total volume of aquifer =Vw/Va.
It has no units. It's a ratio.
The Specific yield of WELL = specific capacity OF WELL = option D,
Unit is m3/sec/m2/m or in short per second. (1/sec).
Hence, discharge of well = sp. capacity x volume.

@Saqib.
You are right. The others are confusing well and aquifer definitions.
The correct answer is of course (D).
