The answer is C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.

Explanation:
The answer is they produce endospores.
Explanation:
The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.
During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.
Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
