Step 1: Recall what induced recharge means.
Induced recharge happens when pumping near a river pulls surface water down into the aquifer to make up for the water being withdrawn.
Step 2: Think about the condition needed for that flow.
Water only moves from a higher level to a lower one, so the river's water surface has to sit above the groundwater table for river water to actually infiltrate toward the well.
Step 3: Check the other options.
A dry river has no water to give, a confined aquifer is sealed off from the river by an impermeable layer, and clayey soil resists infiltration, so none of those support induced recharge the way a higher river level does.
