With the increase in its capacity-inflow ratio, the trap efficiency of...
Explanation:
Increasing the capacity-inflow ratio of a reservoir means that the amount of water entering the reservoir is increasing compared to the storage capacity of the reservoir.

Trap Efficiency:
Trap efficiency is a measure of how well a reservoir is able to trap sediment or other materials that flow into it.

Impact of Capacity-Inflow Ratio:
When the capacity-inflow ratio increases, it means that the reservoir is receiving more water than it can hold. This leads to a faster flow-through of water, reducing the residence time of water in the reservoir.

Effect on Trap Efficiency:
- Increases: With a higher capacity-inflow ratio, the trap efficiency of the reservoir increases because the faster flow-through of water prevents sediment from settling down and getting trapped in the reservoir.
Therefore, the correct answer is option 'A' - increases.

With the increase in its capacity-inflow ratio, the trap efficiency of...
The trap efficiency of a reservoir is affected by its capacity-inflow ratio. This ratio is the storage capacity of the reservoir divided by the annual inflow volume. Generally, as the capacity-inflow ratio of a reservoir increases, the trap efficiency also increases. This is because a larger or deeper reservoir has more volume to trap sediments before they can be discharged.
Hence, the correct answer is: increases.
