The correct answer is Option (1) → Genetic modification has helped to increase the post harvest losses.

Option (1) Genetic modification has helped to increase the post harvest losses. — An incorrect statement. GM has helped to reduce post-harvest losses; the word ‘increase’ makes the line false.

Option (2) Genetic modification has made crops more tolerant to abiotic stresses. — A correct statement. GM crops tolerate cold, drought, salt and heat better.

Option (3) Genetic modification has increased efficiency of mineral usage by plants. — A correct statement. GM plants use minerals more efficiently, and this prevents early exhaustion of fertility of soil. It is one of the gains of genetic modification listed in the book.

Option (4) Genetic modification has reduced reliance on chemical pesticides. — A correct statement. Pest-resistant crops such as Bt cotton make their own toxin against the pest, so they need fewer chemical sprays.
