Hint: Wheat is the cereal and a staple crop in North India. It is a monocot plant similar to the grass variety. Most of the losses in the yield of the agricultural crops are mainly due to the pests and the insects. They cause several damage to the plants and also cause the yield undesirable for consumption.

Complete Answer:
- The wheat plants are affected by many diseases. Out of which the wheat rust is the most common. It is also called leaf rust or the brown rust.
- The main symptoms of this disease are the reddish brown fruiting bodies formed on the surface of the leaves. These bodies again produce several spores causing the entire leaf covered by the rust. This causes the reduction of the photosynthesis in the wheat, since leaves are the site for the photosynthesis.
- This disease is caused by the fungi puccinia. It also affects the plants of the barley, rye stem, leaves and also grains. But these are prevalent in the leaves. This fungi possess both the sexual and the asexual lifecycle. This causes the loss up to twenty percent in the total production.

Thus the option (B) is correct.

Note: There are many foliar fungicides like triazol, Sulphur, captan, mancozeb etc. to control the rust in the plants. Using the genetically resistant wheat varieties to get the best results. Using the seed treated with the fungicide varies may control this disease.
