Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Mycoplasma are considered the smallest living cells known. Reason (R): Mycoplasma completely lack a cell wall and can survive without oxygen. In the light of the above statements, choose the correct answer from the options given below:

Options

  1. ABoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A).
  2. BBoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A).
  3. CAssertion (A) is correct but Reason (R) is not correct.
  4. DAssertion (A) is not correct but Reason (R) is correct.

Correct answer

A. Both Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A).

Step-by-step solution

Assertion (A) is correct because Mycoplasma are indeed the smallest living cells known. Reason (R) is also correct as Mycoplasma completely lack a cell wall and can survive without oxygen. However, the lack of a cell wall and the ability to survive without oxygen do not explain why they are the smallest living cells. These are independent factual characteristics of Mycoplasma. Therefore, both Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A). Answer: Both Assert
