Answer:

Correct Answer: D

Solution:

  • Exp. [d] Capturing $ CO _2 $ from the major stationary sources and its storage into deep geological formations is considered as a potential mitigation option. Geological storage of $ CO _2 $ can be undertaken in a variety of geological settings in sedimentary basins. The options for $ CO _2 $ are as follows ? Depleted oil and gas reservoirs ? Use of $ CO _2 $ in FOR ? Deep unmineable coal seams/enhanced coalbed methane E25M) recovery ? Oceans ? Deep unused saline water-saturated formations ? Other geological media are basalts, shales, and cavities ? Subterranean deep saline formations
