@all.
Repelling groynes are used to move away the water it means don't allow water to erose the bank of river. So the answer is correct.

A is the correct answer.
Because groynes are the structure provided perpendicular to the flow of the river to project bank up it certain distance U/S and D/S.

Repelling groynes are built with their head towards upstream with an inclination of 60 to 80 degrees with the bank. They repel the water flow towards the bank on which it is located.
Repelling Groyne.
The head portion of repelling groynes is under the main attack by the flow. Hence, it should be built with strong protection. The sediments carried by the water gets deposited in the silt pocket which is formed at the upstream side of repelling groyne. These groynes are more advantageous than attracting groynes and are used widely for river training and bank protection.
