Answer 1

Answer: (A), (B), (D)

The correct options are
A Choosing better quality of seeds and crops.
B Protecting crops from weeds, pests and diseases.
D Using high yield management methods.

Demand for food increases as the population increases. If the food requirements cannot be met, it may lead to a food shortage crisis.

To get high yield 3 types of methods are being used:

$\bullet$ Crop variety improvement: Choosing better quality of seeds and crops.
$\bullet$ Crop production management: Adopting methodologies to ensure better yield.
$\bullet$ Crop protection management: Protecting crops from weeds, pests and diseases.

High dosage or overuse of chemical fertilisers increases the toxicity in soil and negatively affects the crop productivity.
