Task: Answer the multiple-choice question.
Question: Which drug has a 19.732\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] Cc1ccc([N+](=O)[O-])c(OCCN2CCNCC2)c1.O=C(O)C(=O)O
[b] Cc1ccc(CN2C(=O)N/C(=C\c3ccc(N4CCOCC4)cc3)C2=O)cc1
[c] CN(C(=O)CSc1nnnn1-c1ccc(O)cc1)C1CCS(=O)(=O)C1
Answer: c. CN(C(=O)CSc1nnnn1-c1ccc(O)cc1)C1CCS(=O)(=O)C1
