Crops are protected from disease-causing fungi by use of fungicides or by the use of genetically engineered fungi-resistant crop
Mkey [24]

Correct answer: C). Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.  

Fungicide is a chemical substance that is known to cause toxicity in fungi in order to kill them. Its use can help to reduce the number of fungal infection that causes great loss to plants and its productivity.

In genetic engineering, the DNA of plants is altered in such a way that it produces a toxic protein, which will kill the fungi when it tries to infect them or slow down the growth of the plant.
