b. surface mining
o
c. coal burning
o
d. hydraulic fracturing

Answer is option A.

The process shown is Crude oil processing.

Explanation:

Crude oil (naturally occurring hydrocarbon) is found deep underground. It is extracted by oil rigs (apparatus constructed for oil drilling) on land and on the oceans. It is piped directly to refineries on land. At sea, huge oil tanker trucks transport crude oil from oil rigs to the refineries.

In the refineries, crude oil is refined to produce various petroleum products like gasoline, petrol, diesel, heating oils, ethylene, polyethylene, naphtha, bitumen, jet fuel, etc. Here, the crude oil is heated and introduced into the distillation tower. Oil is broken down into various petroleum products in the tower. After the distillation, these products are further refined through different processes like cracking, reforming, etc.
