Question

Both power and manure are provided by
a) Petrocrops
b) Nuclear plants
c) Biogas
d) Energy crops

Answer 1

Hint: Energy derived from the utilization of physical and chemical resources such as water, fuels, etc. is known as power. The organic matter made from animal dropping, human feces, and leftover organic waste from plants used as fertilizers is known as manure.

Complete answer:
Petro-crops are the plants that manufacture crude oil or petroleum compounds as a supplement to gasoline or petrol. Some plants and algae manufacture hydrocarbons, ethyl alcohol, etc., that may function as an actual and potential supply of energy. Such plants are units called petro-crops. Some examples of petro cops are Pedilanthus macrocarpus, Calotropis procera, Jatropha curcas, and Copaifera langsdorffii.
Nuclear power stations are a kind of power plant that uses the method of nuclear fission to produce electricity. they are doing this by using nuclear reactors together with the temperature unit cycle, wherever the heat generated by the reactor converts water into steam, that spins a rotary engine and a generator.
Biogas generally refers to a combination of various gases made by the breakdown of organic matter within the absence of oxygen. Biogas is made from raw materials like agricultural waste, manure, municipal waste, dead plants, sewage, environmentally friendly waste, or food waste.
Energy crops are low-priced and low-maintenance crops fully grown entirely for energy production by combustion. The crops are processed into solid, liquid, or vaporized fuels, like pellets, bioethanol, or biogas. They are not produced for consumption. Some of the energy crops are woody plants such as willow.

Hence, the correct option is (C).

Note:
Biogas is created through the refining of various sorts of organic waste. It’s a renewable and environmentally friendly fuel made up of $100\%$ regional feedstocks that's appropriate for a diversity of uses together with road vehicle fuel and industrial uses. The circular-economy impact of biogas production is additionally increased by the organic nutrients recovered within the production method.
