Introduction: The coal serves as the major source of the fuel. However, the coal burning has many cumulative effects that causes many long-lasting environmental change. Thus scientist has named a new geological epoch termed as Anthropocene.

Explanation of Solution
Correct answer: Option b. The humanity’s role in changing the land and air of the planet.
Reasons for the correct answer:
The Anthropocene is the geological epoch that describes the alteration in the atmospheric, hydrologic, geological processes by the activity of humans.
Option b. is given as “humanity’s role in changing the land and air of the planet.”.
Hence the correct option is option b.
Reasons for the incorrect answers:
Option a. is given as “the industrialization of agriculture”. The Anthropocene does not describe the industrialization of agriculture instead it deals with the impact of human activity on environment. Hence, option a. is incorrect.
Option c. is given as “a natural warming of Earth’s atmosphere unrelated to human activity”. The Anthropocene deals with the impact of human activity on environment instead of natural warming. Hence, option c. is incorrect.
Option d. is given as “an end to the continued biological evolution of humans”. The Anthropocene deals with the impact of human activity on environment. Hence, option d. is incorrect.
Therefore, options a., c., and d. are incorrect.
Thus the Anthropocene is defined by humanity’s role in changing the land and air of the planet.
