Problem statement: Answer the multiple-choice question.
Query: Which drug has a -1.877\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCc1ccco1
b) CS(=O)(=O)N(CC(=O)NCc1ccco1)c1ccc2c(c1)OCO2
c) CC(C)Oc1ccc(C2CC(=O)N(c3ccc(N(C)C)cc3)C2=O)cc1
Answer: a. O=C(/C=C/c1cccc([N+](=O)[O-])c1)NCc1ccco1
