Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand mammalian classification.
Mammals are classified into monotremes, marsupials, and placental mammals.
Step 2: Identify monotremes.
Monotremes are egg-laying mammals such as platypus and echidna.
Step 3: Key characteristic.
Despite laying eggs, they produce milk to feed their young.
Step 4: Analyze other options.
Whales and dolphins are placental mammals, marsupials give birth to underdeveloped young.
Step 5: Evolutionary significance.
Monotremes represent primitive mammalian traits.
Step 6: Conclusion.
Thus, monotremes are the correct answer.
Mammals are classified into monotremes, marsupials, and placental mammals.
