Which one of the following is not mined in the delta region of West Bengal?
- a.Natural gas
- b.Clay
- c.Sand
- d.Groundwater
Answer: (D) Groundwater
Natural gas, clay and sand are all genuinely extracted/mined resources in the delta region, whereas groundwater is pumped or drawn, not "mined" in the geological resource-extraction sense, making it the odd one out.
