Highlight any four areas where genetic modification of plants has been useful.

(N/A) $(i)$ Made crops more tolerant to abiotic stresses (cold,drought,salt,heat).
$(ii)$ Reduced reliance on chemical pesticides (pest-resistant crops).
$(iii)$ Helped to reduce post-harvest losses.
$(iv)$ Increased efficiency of mineral usage by plants (this prevents early exhaustion of soil fertility).
$(v)$ Enhanced nutritional value of food,e.g.,Vitamin $A$ enriched rice.
