Read the following Assertion and Reason and choose the correct option.
Assertion: Alien species introductions, whether unintentional or deliberate, can lead to the decline or extinction of indigenous species, as exemplified by the extinction of more than 200 species of cichlid fish in Lake Victoria due to the introduction of the Nile perch.
Reason: Co-extinctions occur when a species becomes extinct, leading to the extinction of other plant and animal species associated with it in an obligatory way, such as parasites or coevolved plant-pollinator mutualism.

Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion and Reason are false
Correct answer
B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
Step-by-step solution
The Assertion accurately states that alien species introductions can result in the decline or extinction of indigenous species, demonstrated by the example of the Nile perch leading to the extinction of more than 200 species of cichlid fish in Lake Victoria. The Reason provides the correct explanation by mentioning co-extinctions, where the extinction of one species leads to the extinction of other plant and animal species associated with it in an obligatory manner, as seen in the case of parasites or coevolved plant-pollinator mutualism. This explanation aligns well with the example mentioned in the Assertion, supporting the truth of both the Assertion and Reason.
