Column I (Animals): i. Spider; ii. Coelenterates; iii. Frog; iv. Fishes
Column II (Respiratory organs / surface): a. Internal gills; b. Book lungs; c. Plasma membrane; d. Lungs; e. External gills
Choose the correct option

• A. i - b, ii - c, iii - d, iv - e
• B. i - b, ii - c, iii - d, iv - a
• C. i - c, ii - e, iii - a, iv - b
• D. i - e, ii - c, iii - d, iv - a

Hint:

Answer 1

The Correct Option is B

Step 1: Understanding the Concept

Coelenterates exchange gases through the plasma membrane by diffusion (c).
Frog breathes mainly through lungs (d) in the adult.
Fishes have internal gills (a).

Step 3: Select the Option
The set i-b, ii-c, iii-d, iv-a is given in option B.

Final Answer:
The correct matching is i-b, ii-c, iii-d, iv-a. \[ \boxed{\text{(B) }\text{i - b, ii - c, iii - d, iv - a}} \]
