The option that BEST explains the source of the problem of high alkalinity in the well water is:
The groundwater is flowing through rocks containing carbonates.
This is because carbonates, which are naturally occurring minerals found in many types of rocks (such as limestone), can increase the alkalinity of water as they dissolve. This process raises the pH of the water, making it more alkaline, which can indeed affect a plant's ability to absorb water.
