Step 1: Understanding the Concept
Many antibiotics come from Streptomyces species, while griseofulvin comes from a mould.
Step 2: Match
Chloromycetin comes from Streptomyces venezuelae (III).
Erythromycin comes from Streptomyces erythreus (IV).
Griseofulvin comes from Penicillium griseofulvum (I).
Terramycin is paired with Streptomyces aureofaciens (II).
Step 3: Write the pairs
A-III, B-IV, C-I, D-II.
Final Answer:
The correct matching is A-III, B-IV, C-I, D-II.
\[ \boxed{\text{(A) }\text{A-III, B-IV, C-I, D-II}} \]
