Task: Answer the multiple choice question.
Question: Which drug has a 2.374\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC(=O)NC(CCS(C)(=O)=O)C(=O)Nc1c(C)cccc1C
b O=C(COc1ccc(/C=N/NC(=O)c2cc3ccccc3o2)cc1Cl)Nc1ccccc1
c COc1ccc(C2NCc3ccc4c(c3-n3cccc32)OCO4)cc1OC.Cl
d Cc1csc(NC(=O)c2cc(C)oc2C)n1
Answer: c. COc1ccc(C2NCc3ccc4c(c3-n3cccc32)OCO4)cc1OC.Cl
