Given below are assertion and reason. Point out if both are true with reason being correct explanation (A), both true but reason is not correct explanation (B), assertion true but reason is wrong ( C ), both are wrong (D). Assertion : Analogous organs are a result of divergent evolution Reason : Eye of Octopus and that of mammals depict divergent evolution.

(a) If both the assertion and reason are true and reason is a true explanation of the assertion. (b) If both the assertion and reason are true but the reason is not the correct explanation of assertion. (c) If the assertion is true but reason is false.
