The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept:
Pole and line is a selective fishing method used to catch schooling pelagic fish, particularly tuna, using a rod, line, and hook.

Step 2: Detailed Explanation:

In commercial pole-and-line fishing, speed is essential when a school of tuna is active near the vessel.
Barbless hooks (often decorated with feathers or plastic lures) are used so that once a tuna is swung onboard, it can be easily unhooked with a quick flick of the rod.
This allows the fisher to return the line to the water immediately, maximizing the catch rate during feeding frenzies.

Step 3: Final Answer:

Therefore, barbless hooks are used in commercial tuna pole and line operations.
