Q. Main objective of production/use of herbicide resistant GM crops is to
A) Reduce herbicide accumulation in food articles for health safety
B) Eliminate weeds from the field without the use of manual labour
C) Eliminate weeds from the field without the use of herbicides
D) Encourage eco-friendly herbicides
Explanation
[Solution from source] Herbicide-tolerant crops survive a broad-spectrum herbicide that kills the weeds around them, so fields can be weeded chemically instead of by manual labour. Herbicides are still sprayed, so 'without the use of herbicides' is wrong. Answer (2).
