Question

Match List I with List II

Choose the correct answer from the options given below:

• A. A - I, B - II, C - IV, D - III
• B. A - II, B - I, C - IV, D - III
• C. A - II, B - I, C - III, D - IV
• D. A - III, B - I, C - IV, D - II

Hint:

- Marine Borers (e.g., Teredo, Martesia): Destroy the wood structurally.
- Marine Foulers (e.g., Barnacles, Mussels): Attach to the surface, increasing fuel consumption by raising hydrodynamic drag.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Wooden fishing vessels are highly vulnerable to degradation by marine organisms, requiring specialized construction and maintenance techniques to ensure durability.

Step 2: Detailed Explanation:
Let us establish the correct matches between the terms:
- A. Teredo (shipworm): A notorious wood-boring bivalve mollusc, classified as a Marine borer (II) that destroys wooden hulls.
- B. Barnacles: Sessile crustaceans that attach firmly to submerged surfaces, acting as a major Marine fouler (I) that increases vessel drag.
- C. Water proof hull: Achieved during traditional wooden boat building by sealing the gaps between hull planks with oakum and pitch, a process called Caulking (IV).
- D. Hull protection: Historically, wooden hulls were covered with thin sheets of copper, known as Copper sheathing (III), to protect them from boring molluscs and weed attachment.
Therefore, the correct match is: A - II, B - I, C - IV, D - III.

Step 3: Final Answer:
This sequence of matches corresponds to option (B).
