Crops are protected from disease-causing fungi by use of fungicides or by the use of genetically engineered fungi-resistant crops. Which statement BEST describes how the two techniques differ in reducing fungal infestations of crop plants?

A) Fungicides kill plants infected with fungi, while genetic engineering modifies fungal DNA.
B) Fungicides kill the source of food for fungi, while genetic engineering helps to make fungi-infected plants edible.
C) Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.
D) Fungicides change fungal DNA, while genetic engineering helps the crops and the fungi to form a symbiotic relationship.

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.
