Assertion and Reason Evaluation:
Assertion: The design made by the veins of a leaf is called the leaf venation.
Reason: There is only one type of leaf venation.
Evaluation:
Option A: Assertion and reason both are correct statements and reason is a correct explanation for the assertion.
This option is incorrect because there are actually two main types of leaf venation - parallel venation and reticulate venation. Therefore, the reason provided is not accurate in stating that there is only one type of leaf venation.
Option B: Assertion and reason both are correct statements and reason is not a correct explanation for the assertion.
This option is the correct choice. The assertion is true in stating that leaf venation refers to the design made by the veins of a leaf. However, the reason is incorrect as it states that there is only one type of leaf venation, which is not accurate.
Option C: Assertion is a correct statement but the reason is a wrong statement.
This option is incorrect because the assertion is true, but the reason is also incorrect. There is more than one type of leaf venation, as mentioned earlier.
Option D: Assertion is a wrong statement but the reason is a correct statement.
This option is incorrect as the assertion is actually a correct statement. Leaf venation does refer to the design created by the veins in a leaf.
Therefore, the correct choice is Option B: Assertion and reason both are correct statements, but the reason is not a correct explanation for the assertion.
