Task: Answer the multiple-choice question.
Query: Which compound has a 4.746\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(CSCc1ccc([N+](=O)[O-])cc1)NN=C1CCCCCC1
[b] O=C(O)CCS(=O)(=O)Cc1ccccc1Cl
[c] O=C(CSc1nc2ccccc2s1)N/N=C/c1cc([N+](=O)[O-])ccc1O
Answer: b. O=C(O)CCS(=O)(=O)Cc1ccccc1Cl
