Question

Given below are four matchings of an animal and its kind of respiratory organ:

1. Silver fish – trachea
2. Scorpion – book lung
3. Sea squirt – pharyngeal gills
4. Dolphin – skin

The correct matchings are:
 

• A. A and D
• B. A, B and C
• C. B and D
• D. C and D

Answer 1

The Correct Option is B

To determine the correct matchings of the given animals with their respective respiratory organs, let's analyze each option individually:

1. Silver fish – trachea: Silverfish belong to the arthropods group, and like many insects, they use a tracheal system for respiration. Therefore, this matching is correct.
2. Scorpion – book lung: Scorpions are arachnids, and they respire using book lungs, which are a series of thin membranes resembling pages of a book. Thus, this matching is correct.
3. Sea squirt – pharyngeal gills: Sea squirts are marine animals that use pharyngeal gills for respiration as part of their filter-feeding process. Hence, this matching is correct.
4. Dolphin – skin: Dolphins are mammals and use lungs for breathing, not their skin. Therefore, this matching is incorrect.

Based on the analysis, the correct matchings are options A, B, and C.
