1. Attracting Groyne-pointed downstream and at an angle of 45-60° with downstream.
2. Deflecting Groyne-pointed upstream and at an angle of 20-30° with normal of the bank.
3. Repelling Groyne-At an angle of 90° with the bank.
Beside that T shape and inverted hocky shape Groyne also placed according to uses.
So I think the answer will all the above as not mentioning the type of Groyne is.

Ans B is correct because it shows that it is repelling Groyne which is designed at an angle 60 to 80 degree to upstream.
i.e. 10-30 degree normal to the river bank.
