Question

Assertion (A): Maize is resistant to stem borers

Reason (R): This is due to high aspartic acid, high nitrogen and high sugar content in maize

• A. Both the assertion and reason are true and the reason is the correct explanation of the assertion
• B. Both the assertion and reason are true but the reason is not the correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both the assertion and reason are false

Answer 1

The correct option is C Assertion is true but the reason is false

Agricultural pests are organisms that attack agricultural crops and destroy them, leading to huge crop losses. Some crop plants naturally develop resistance to pests as a result of morphological, physiological or biochemical characteristics in them.

In maize crop certain biochemical characteristics like low nitrogen, low sugar and high aspartic acid content helps resist against maize stem borers (insect larvae which bore into plant stems).

Hence, assertion is true but the reason is false
