Restoration of damaged coral reefs
B)
Development of building materials using plant residues
C)
Identification of areas for exploration/extraction of shale gas
D)
Providing salt licks for wild animals in forests/protected areas.

Correct Answer : Option (A) - Restoration of damaged coral reefs

Note :

BIOROCK OR Mineral Accretion Technology is a coral reef restoration technology that utilizes low voltage electricity to improve the health and growth rates of corals and other marine organisms. 
 
The technology works by passing a small amount of electrical current through electrodes in the water.

When a positively charged anode and negatively charged cathode are placed on the seafloor, with an electric current flowing between them, calcium ions combine with carbonate ions and adhere to the structure (cathode).

This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly.

Fragments of broken corals are tied to the biorock structure, where they are able to grow at least four to six times faster than their actual growth as they need not spend their energy in building their own calcium carbonate skeletons.
