Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and fluid velocity is at its maximum.

Venna is point of minimum area of stream flow, which occurs after throat due to sudden compaction and hence its diameter is less than orifice diameter.

The distance of vena-contracta from the orifice is half the diameter of the orifice.
So, The option (D) should be correct.
