P-3, Q-4, R-2, S-1
P-2, Q-4, R-1, S-3
P-4, Q-3, R-2, S-1
The Correct Option is C
Solution and Explanation
To match the morphological features or life processes in Group I with corresponding organisms in Group II, we need to understand the characteristics of each term and the class of organisms they relate to:
- Water vascular system is a characteristic feature of marine invertebrates belonging to the phylum Echinodermata. It is involved in locomotion, feeding, and respiration. Therefore, P matches with 2 (Echinodermata).
- Molting, also known as ecdysis, is the process of shedding the exoskeleton to allow growth in arthropods. Trilobita, which are extinct marine arthropods, underwent molting. Therefore, Q matches with 4 (Trilobita).
- Jet propulsion locomotion is a method of movement that involves expelling water forcefully to propel the organism forward. Cephalopods, like squids and octopuses, use this mode of propulsion. Therefore, R matches with 1 (Cephalopoda).
- Lophophore is a specialized feeding structure found in certain aquatic animals, such as those belonging to the phylum Brachiopoda. Therefore, S matches with 3 (Brachiopoda).
Thus, the correct matching is: P-2, Q-4, R-1, S-3.
