Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Over watering of chrysanthemum plants is very harmful for their proper growth and development.
Reason (R): Over watering cause yellowing of leaves and mortality of plants due to rotting of roots.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

Chrysanthemums are highly susceptible to root rot caused by wet, poorly drained soils. Always ensure a well-drained growing medium to avoid waterlogging and root decay.

Answer 1

The Correct Option is A

The given question involves an assertion and a reason regarding the effect of over-watering chrysanthemum plants. Let's analyze both statements step by step:

1. Assertion (A): "Over watering of chrysanthemum plants is very harmful for their proper growth and development."
   • Over watering can lead to several issues in plants such as poor growth, yellowing of leaves, and even plant death.
2. Reason (R): "Over watering cause yellowing of leaves and mortality of plants due to rotting of roots."
   • When plants receive excess water, it suffocates the roots by cutting off the air supply, leading to root rot.
   • Root rot prevents the plant from absorbing nutrients properly, causing the leaves to turn yellow and potentially leading to plant death.
3. Assessment:
   • Both the assertion and the reason are true. Over watering is indeed harmful as it can result in root rot, which subsequently leads to the yellowing of leaves and mortality.
   • The reason clearly provides the correct explanation for why the assertion is true.

Therefore, the correct answer is that Both (A) and (R) are correct and (R) is the correct explanation of (A).
