Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Ornithorhynchus and Aptenodytes are both oviparous animals. Reason (R): Ornithorhynchus is a mammal whereas Aptenodytes is a bird. 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 true and Reason (R) is the correct explanation of Assertion (A).
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

  4. DAssertion (A) is false but Reason (R) is true.

Correct answer
