Question

Assertion (A): Presently, most of the commercially important marine fish species are endangered
Reason (R): Humans overharvest certain marine species of fish.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true and R is not the correct explanation of A
• C. A is true, but R is false
• D. A is false, but R is true

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A

Humans depend on nature for various needs such as shelter, food etc. Nature certainly has resources to fulfil the needs, but humans have started to over exploit the natural resources and this has caused the extinction of species.

The Steller’s sea cow (aquatic mammal) and passenger pigeon were driven to extinction by humans hunting it for food. The extinction of many such species is due to over exploitation by humans.

Presently, most of the commercially important species of marine fish are endangered as these are overharvested (excessive fishing) by humans. A species is said to be endangered when it is facing the risk of extinction.

Hence, both assertion and reason are true and reason is the correct explanation of assertion.
