Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.973% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CC(=O)c1ccc(NC(=O)C2=CC(c3cccs3)=NS(=O)(=O)N2C)cc1
(b) CNC(=O)c1cc2ccc(OC)cc2oc1=O
(c) Cc1ccc(NC(=S)NNC(=O)c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)cc1Cl
(d) CC(C)c1ccc(/C=N/Nc2ccc(C(=O)O)cc2)cc1
Answer: b. CNC(=O)c1cc2ccc(OC)cc2oc1=O
