Solution

The correct option is C Grow and multiply in very deep marine sediments.
The prokaryotic organisms are found in different places and especially in the aquatic habitats. There are prokaryotes which can live in the depths of seas and oceans. As we move to the depth of the marine habitats, there is an increase in the pressure. The prokaryotic organisms which have adapted to survive in the sediments where there is increased pressure are known as barophilic prokaryotes. They can divide, grow and colonise the sediments in the aquatic habitats. 
Thus, the correct answer is option C.
