Question

Complete the following analogy with respect to classification of mammals.
Marsupials : (i) :: monotremes : (ii)

• A. (i) pouched mammals, (ii) placental mammals
• B. (i) pouched mammals, (ii) egg laying mammals
• C. (i) placental mammals, (ii) egg laying mammals
• D. (i) placental mammals, (ii) pouched mammals

Hint:

3 types of mammals: Monotremes (egg) $\rightarrow$ Marsupials (pouch) $\rightarrow$ Placental

Answer 1

The Correct Option is B

Concept: Mammals are classified into three main groups based on their mode of reproduction.
• Monotremes: Egg-laying mammals (e.g., platypus)
• Marsupials: Pouched mammals (e.g., kangaroo)
• Placental mammals: Develop embryo inside uterus with placenta

Step 1: Understand marsupials.
Marsupials give birth to underdeveloped young, which develop further in a pouch.

Step 2: Understand monotremes.
Monotremes lay eggs but are still classified as mammals.

Step 3: Match analogy.
• Marsupials $\rightarrow$ Pouched mammals
• Monotremes $\rightarrow$ Egg-laying mammals

Step 4: Analyze options.
• (A) Incorrect
• (B) Correct
• (C) Incorrect
• (D) Incorrect

Step 5: Conclusion.
Thus, the correct analogy is pouched and egg-laying mammals. Final Answer: Option (B)
