Answer: The correct answer is -
D) in a host, it is capable of reproduction.
Explanation:
Virus can be described as a microscopic, infective, non living agent that typically possesses genetic material (DNA or RNA) that is surrounded by a proteinaceous coat (capsid).
It can not replicate by its own and thus it uses host machinery for replication. In other words, it multiplies within host organism. This is the reason that it can be called as living.
Thus, option D) is the right answer.
Deposition from flow into a lake or an ocean
A delta is a feature of a river that occurs at its mouth whereby the river tends to drains into a water body (ocean or lake) through several drainages.
Explanation:
As a river approaches and drains into a water body, like a lake or ocean, it deposits a lot of sediments that it collected upstream. The high gradient upstream gives the river a high energy flow enabling it to have high erosion power and it can carry lots of sediments. The geographical gradient lowers closer to the mouth of the river and much of the sediments settle down due to the low speed and energy of the river flow at this stage. Over years, the sediment accumulates over a large area and the river has to find several channels to drain into the ocean or lake. This forms a delta.

Answer: d. migration away from productive growing areas
Explanation:
The rice, corn and wheat are the basic food crops. These crops are used for making several dishes their flour as well as the grains of rice and corn are eaten when cooked. These three crops are necessary to be grown on large scale to meet the basic food requirements of the large growing population worldwide. The plant roughage of these three crops can be used to make biofuels. These are used as a fodder crops to feed poultry and cattles for meat harvest.
The demand will also increase when one is migrated to an unproductive region. However, the increased demand is due to decreased supply and not because of increased consumption hence, it will not directly contribute to increase in demand of crops.
