Answer :
The correct answer is C. High with small gates.
In a barrage, the crest level is typically high with small gates. A barrage is a type of dam or barrier that is designed to prevent the flow of water or other materials, such as sediment or debris, from one body of water to another. The crest level refers to the height of the dam or barrier, and it is usually high to ensure that it can effectively control the flow of water or other materials. The gates at the crest level are typically small to allow for precise control of the flow and to prevent excessive pressure on the dam or barrier.
