Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Development of different functional structures from a common ancestral form is called adaptive radiation. Darwin's finches of the Galapagos island had common ancestors but now have different types of modified beaks according to their food habits. Darwin differentiated thirteen species of finches and grouped them into six main types.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
