Some prokaryotes are able to survive unfavorable conditions by forming
A
bacteriphage
B
facultative anaerobes
C
obligate anaerobes
D
None of the above
Explanation: 

Detailed explanation-1: -Almost all prokaryotes have a cell wall, a protective structure that allows them to survive in both hyper-and hypo-osmotic conditions. Some soil bacteria are able to form endospores that resist heat and drought, thereby allowing the organism to survive until favorable conditions recur.

Detailed explanation-2: -Many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. Certain prokaryotes, like Clostridia bacteria, are obligate anaerobes. Obligate anaerobes live and grow in the absence of molecular oxygen.

Detailed explanation-3: -Prokaryotes may perform aerobic (oxygen-requiring) or anaerobic (non-oxygen-based) metabolism, and some can switch between these modes.

Detailed explanation-4: -Facultative anaerobes In anaerobic conditions (i.e., O2 deficient environment) these organisms survive and grow by either fermentation or anaerobic respiration, while, in the oxygenated environment these organisms switch to aerobic respiration.
