Respuesta :
(A) is the correct option
Explanation:
- Hydrothermal vents, also known as deep sea vents are the aftermath of a volcanic eruption due to shifting of the plates that form the Earth’s crust
- Black smokers are formed due to the high pressure at this depth and temperature of the trapped water because of which there is low oxygen content of water
- The black smokers emit fluids and causing it to emit chemicals such as sulfide, iron, copper and zinc
- Barophiles are organisms whose survival and reproduction is optimized to high pressures, such as those in deep sea environments
- Psychrophiles are microorganisms that can grow at 0 °C and below, have an optimum growth temperature close to 15 °C, and usually do not survive at temperatures above 20 °C
- They are found in permanently cold environments such as the deep waters of the oceans and because they are active at low temperature, psychrophiles are important decomposers in cold climates
