Read Assertion (A) and Reason (R) carefully :

Assertion (A) : Domestication of animals was a gradual process that took place in many parts of the world.

Reason (R) : The earliest domesticated animals include sheep and goat.

Choose the correct option.

Let us analyze the Assertion (A) and Reason (R) individually to determine their correctness and their logical relationship.

Analysis of Assertion (A):
"Domestication of animals was a gradual process that took place in many parts of the world."
Domestication of animals and plants was indeed a slow, gradual process that began about 12,000 years ago. It occurred independently in various regions across the globe (such as the Fertile Crescent, East Asia, Mesoamerica, and the Andes) rather than starting in just one single location. Therefore, Assertion (A) is true.

Analysis of Reason (R):
"The earliest domesticated animals include sheep and goat."
Historically and archaeologically, sheep and goats were among the earliest animals to be domesticated by humans, starting around 10,000 to 11,000 years ago in southwest Asia. Therefore, Reason (R) is also true.

Analyzing the Relationship:
While both statements are historically correct, the fact that sheep and goats were among the earliest domesticated animals does not explain why or how domestication was a gradual, worldwide process. The reason describes specific examples of early domesticated animals, whereas the assertion describes the general, global, and temporal nature of the domestication process. Thus, Reason (R) is not the correct explanation for Assertion (A).

Therefore, both A and R are true but R is not the correct explanation of A.
