A Correct answer
Explanation

Both assertion as well as reason statements is correct and R is correct explanation of A. Halophiles are salt-loving organisms that flourish in hypersaline environments and can be classified as slightly, moderately or extremely halophilic, depending on their requirement for salt concentration. They include both prokaryotic as well as eukaryotic microbes with the capacity to balance the osmotic pressure of the environment and resist the denaturing effects of salts.
