Answer:
All living things are made of cells
Cells form from previously existing cells
Explanation:
According to the Cell Theory, all forms of life are composed of one or more cells, whereby cells are the fundamental building blocks in all living organisms. All cells are composed of inorganic molecules (e.g., water) and carbon-based organic molecules (e.g., carbohydrates, lipids, nucleic acids, etc). All the new cells arise from the division of pre-existing cells. Louis Pasteur showed cells would only grow in broth if they are exposed to air (oxygen), thus refuting the idea of spontaneous generation. In multicellular eukaryotic organisms, these cells can be organized in tissues, organs and organ systems.

A river that is diverted to the irrigating farmland during a drought is an example of the human-caused disturbances to an ecosystem.
An ecosystem refers to a particular community within which the organisms exist and interact with each other. For example, fresh water ecosystem, desert ecosystem and forest ecosystem.
In the given situation, the river channel is disturbed by changing its flow direction. This is caused by the human activity, that changes the course of the river channel to the farmlands during a flood, so that the water can provide nutrient to the soil and prevent the soil from getting eroded.
Thus, by doing this, the river ecosystem gets affected, as a result of which the organisms existing in this ecosystem such as fishes are affected.
Hence, the correct answer is option (B).
