[A] Improving soil structure and fertility by accelerating mineral decomposition for agricultural purposes.

[B] Capturing and storing atmospheric CO₂ through chemical reactions with crushed silicate rocks.

[C] Increasing the conductivity of groundwater by altering the pH balance of aquifers.

[D] Enhancing the production of geothermal energy by promoting heat transfer in rock formations.

Answer: B
Notes:

Explanation – Enhanced rock weathering involves spreading finely crushed silicate rocks over land, where they chemically react with atmospheric CO₂ to form stable bicarbonates. This process helps sequester carbon dioxide, thereby reducing greenhouse gases in the atmosphere.
