Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In cockroaches, the forewings (tegmina) are not used in flight. Reason (R): Tegmina are transparent and membranous structures that cover the hindwings when at rest. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

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