Step 1: Understanding the Question:
This question tests knowledge of bioinformatics databases and tools.
Step 2: Detailed Explanation:
Bioinformatics databases include:
- ENTREZ (A): A search and retrieval system (not a database itself, but a portal).
- SWISS-PROT (C): A curated protein sequence database.
- GenBank (D): A nucleotide sequence database.
BLAST (B): A search tool, not a database.
It is an algorithm used to compare sequences.
Thus, the databases are ENTREZ, SWISS-PROT, and GenBank.
Step 3: Final Answer:
Thus, A, C, and D are databases, which corresponds to option (C).
