Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.421\% 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=S(=O)(Nc1nc(-c2ccccc2)cs1)c1cc(Cl)ccc1Cl
b) O=C(/C=C/c1ccco1)NCc1ccc2c(c1)OCO2
c) O=C1NC(=O)N(c2ccccc2F)C(=O)/C1=C/c1ccc(Oc2ccc([N+](=O)[O-])cn2)cc1
d) CCc1ccc(NC(=O)C(=O)NCC2CCCO2)cc1
Answer: c. O=C1NC(=O)N(c2ccccc2F)C(=O)/C1=C/c1ccc(Oc2ccc([N+](=O)[O-])cn2)cc1
