Reproductive strategy is described into r-selection strategy and K-selection strategy. When an organism reproduces slowly and has only one offspring each time it reproduces, this organism is classified as the K-selected organism. Examples of K-selected organisms are elephants and humans.

Answer:
Option 3, of the abiotic factors found in their environment
Explanation:
The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.  
The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case,  if a bacteria lives in an environment where temperature is less than -5oC or higher than  50oC, then such habitats are considered to be “habitats with extremities”  as special physiological mechanisms are required to maintain the homeostasis and survive.
Likewise absence of sunlight further adds to the extremities of the habitat.
 Option 3, is correct
 
        
             
        
        
        
Carbon and fluorine combine covalently to form a binary compound. the formula of the compound with the name carbon tetrafluoride is CF4.
