Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.930\% 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 additional words.
Options:
a) O=C(COC(=O)C1CCCCC1)Nc1ccc([N+](=O)[O-])cc1
b) COc1cc(CC(=O)O)ccc1O
c) COC(=O)c1ccc(N2CCN(S(=O)(=O)c3c(C)cc(C)cc3C)CC2)c([N+](=O)[O-])c1
d) O=S(=O)(c1ccc(Cl)cc1)n1cnc2ccccc21
Answer: b. COc1cc(CC(=O)O)ccc1O
