Identify the incorrect fact about genetic modification.

The correct answer is Option (4) → Increase in reliance on chemical pesticides (pest-resistant crops)

Option (1) Crops are made more tolerant to abiotic stresses (cold, drought, salt, heat) — A correct fact. Abiotic stresses are harsh non-living conditions. GM crops can grow and yield even under such conditions.

Option (2) Increase in efficiency of mineral usage by plants — A correct fact. GM plants use soil minerals better, which stops the soil from losing its fertility early.

Option (3) Help to reduce post harvest losses — A correct fact. Less of the crop spoils during storage and transport after it is harvested.

Option (4) Increase in reliance on chemical pesticides (pest-resistant crops) — An incorrect fact. Pest-resistant crops such as Bt cotton make their own insect-killing protein. Farmers therefore need fewer chemical pesticides. Genetic modification has reduced the reliance on pesticides, not increased it.
