Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Solution:
The task is to match each element in List I with the correct element in List II by understanding the characteristics of each species.
- Gorgonia: This is commonly known as Sea Fan, which belongs to the phylum Cnidaria and is characterized by its fan-like structure. Therefore, Gorgonia maps to iii. Sea Fan.
- Pontobdella: This is a type of leech and is specifically known as a Marine leech, an annelid found in marine environments. Therefore, Pontobdella maps to i. Marine leech.
- Balanus: Known as a barnacle, which is a type of crustacean that attaches itself to hard surfaces in marine environments. Specifically, it is known as a Rock barnacle. Therefore, Balanus maps to iv. Rock barnacle.
- Echinus: This is the genus name for Sea Urchin, which is an echinoderm known for its spiny shell. Therefore, Echinus maps to ii. Sea Urchin.
Based on these associations, the correct matches are:
A - iii, B - i, C - iv, D - ii
