Hint:

Guanine crystals give fish their silvery luster; extracting these crystals from the skin/scales creates "Pearl Essence," which is literally the essence of the fish's pearly shine.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The efficient utilization of fish waste involves converting discarded parts (heads, skins, bladders, scales) into valuable industrial and commercial by-products. Each by-product is derived from specific tissues rich in certain biochemical components like collagen or guanine.
Detailed Explanation:
1. Fish Glue (A): While glue can be made from various parts, industrial fish glue is traditionally produced by boiling the heads and occasionally the bones of whitefish (like cod). The collagen in these parts is converted into an adhesive. (A-IV)
2. Fish Maws (B): "Fish maw" is the commercial term for the dried air bladder (swim bladder) of large fish. It is highly prized in Chinese cuisine and is also the source material for isinglass. (B-III)
3. Gelatin (C): Gelatin is obtained by the partial hydrolysis of collagen found in skin and bones. Fish skin is a particularly abundant source of high-quality gelatin used in the food and pharmaceutical industries. (C-II)
4. Pearl Essence (D): This is a luster-providing substance used in the manufacture of artificial pearls and cosmetics. It is made from guanine crystals extracted from the epidermal layer and scales of certain fish like herring. (D-I)

The matching results in: A-IV, B-III, C-II, D-I.

Step 2: Final Answer:
The correct matching sequence is found in Option (B).
