medium
Genetically modified plants have been useful in increasing
A
Crop yield
B
Nutritional value of food
C
Tolerance against abiotic stresses
D
All of the above
Solution
(d)
Genetic modification of crops have resulted in
$(i)$ Increased tolerance against abiotic stresses (cold, drought, salt and heat)
$(ii)$ Reduced reliance on chemical pesticides (pest-resistant crops)
$(iii)$ Reduced post-harvest losses
$(iv)$ Enhanced nutritional value of food, $e . g .$, vitamin- $A$ enriched (golden rice)
