Match List I with List II :

List I		List II
A	Pterophyllum	I	Hag fish
B	Myxine	II	Saw fish
C	Pristis	III	Angel fish
D	Exocoetus	IV	Flying fish

Choose the correct answer from the options given below :

To match the scientific names of the organisms in List I with their common names in List II, we can analyze each genus individually:

1. A. Pterophyllum: Commonly known as the Angel fish. It is a genus of freshwater fish from the family Cichlidae, widely popular in aquariums. Thus, A matches with III.

2. B. Myxine: Commonly known as the Hag fish. It is a jawless fish (class Myxini) known for producing abundant slime. Thus, B matches with I.

3. C. Pristis: Commonly known as the Saw fish. It is a genus of cartilaginous fish characterized by a long, narrow, flattened rostrum lined with sharp transverse teeth, resembling a saw. Thus, C matches with II.

4. D. Exocoetus: Commonly known as the Flying fish. It is a genus of marine fish known for their ability to make gliding flights out of the water using their unusually large pectoral fins. Thus, D matches with IV.

Combining these matches, we get:
A-III, B-I, C-II, D-IV

Therefore, the correct option is A-III, B-I, C-II, D-IV.
