The correct answer is: A. Should be sunk by 20 cm.
The Indian type W.C. is a squatting toilet. It is important to sink the R.C.C. slabs in the toilet portion by 20 cm so that the toilet is at a lower level than the adjacent portion. This will help to prevent water from flowing out of the toilet and into the adjacent area.
Option B is incorrect because the R.C.C. slabs should be sunk, not kept above the adjacent portion.
Option C is incorrect because the R.C.C. slabs should be sunk by 20 cm, not 50 cm.
Option D is incorrect because the R.C.C. slabs should be sunk, not not sunk.
