Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Ans is D. A barophile is an organism that needs a high-pressure environment in order to grow. Barophiles are a type of an extremophile. An example of a methanococcus high-pressure habitat is the deep-sea environment, such as ocean floors and dee lakes where the pressure can exceed 380 atm. The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. Acidophiles are microorganisms that thrive under acidic conditions, usually at very low pH (<3). Natural niches where acidophiles can be found are volcanic areas (Yellowstone), hydrothermal sources, deep-sea vents, metal mining activities (Iron Mountain, Río Tinto) or in the stomachs of animals. Examples of acidophiles include Thiobacillus acidophilus (a type of bacteria), Vorticella (a type of eukaryote), and Crenarchaeota (a type of archaea). Scientists have identified several areas, natural and manmade, that are acidic enough for acidophiles to thrive in. A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from 20 to 45 °C (68 to 113 °F). The term is mainly applied to microorganisms. Examples. Some notable mesophiles include Listeria monocytogenes, Staphylococcus aureus, and Escherichia coli. Other examples of species of mesophiles are Clostridium kluyveri, Pseudomonas maltophilia, Thiobacillus novellus, Streptococcus pyogenes, and Streptococcus pneumoniae.

Answer is (D). Barophiles are the bacteria thriving in extreme pressure environments. Mesophiles are bacteria that grow in moderate temperatures like E. Coli. Acidophile organisms thrive under acidic conditions at pH 2 or below. Halophile are an organism, especially a microorganism, that grows in or can tolerate saline conditions. See for these types of questions I would suggest that you should learn these examples directly because these same would be repeated.
