Understanding the Matchings
In this question, we need to match items from Column I with their respective classifications or characteristics from Column II. Here’s an explanation of each item:
Placoid Scales
- These are the scales found in Chondrichthyes, which include sharks and rays.
- Placoid scales are tooth-like structures that provide protection and help reduce turbulence while swimming.
Ctenoid Scales
- These scales are characteristic of Osteichthyes, or bony fish.
- Ctenoid scales have a comb-like edge and are more flexible compared to other types of scales, providing better movement in water.
Ectoparasites
- Ectoparasites are organisms that live on the outside of a host, often feeding on its blood or tissues.
- An example of ectoparasites includes certain species of leeches and lice, which are commonly associated with Hemichordata and other marine organisms.
Proboscis Gland
- This gland is primarily found in Cyclostomata, which includes lampreys and hagfish.
- The proboscis gland is used for feeding and attachment to hosts, particularly in parasitic species.
Matching Codes
- Based on the definitions and classifications:
- I. Placoid Scales → 1. Chondrichthyes
- II. Ctenoid Scales → 2. Osteichthyes
- III. Ectoparasites → 4. Cyclostomata
- IV. Proboscis Gland → 3. Hemichordata
Correct Answer Explanation
The correct matching is represented by option D (1 2 4 3), indicating:
- Placoid Scales are associated with Chondrichthyes (1).
- Ctenoid Scales are associated with Osteichthyes (2).
- Ectoparasites are linked to Cyclostomata (4).
- Proboscis Gland corresponds with Hemichordata (3).
Thus, option D accurately matches each item from Column I to Column II.

Match each item in Column I with one item in Column II and choose your...
Placoid Scales are characteristic of Chondrichthyes (cartilaginous fishes).
Ctenoid Scales are characteristic of Osteichthyes (bony fishes).
Ectoparasites are typically associated with Cyclostomata (e.g., lampreys).
Proboscis gland is a feature of Hemichordata (e.g., acorn worms).
Thus, the correct code is Option D: 1 2 4 3.
Ctenoid Scales are characteristic of Osteichthyes (bony fishes).
Ectoparasites are typically associated with Cyclostomata (e.g., lampreys).
Proboscis gland is a feature of Hemichordata (e.g., acorn worms).
