Task: Answer the multiple choice question.
Query: Which drug has a 3.397\% hERG inhibition at a concentration of 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(O)Cn1cc(/C=C/[N+](=O)[O-])c2ccccc21
b O=C(Nc1ccc(NC(=O)c2ccco2)nc1)c1ccco1
c CCCCNC(=S)N(C)/N=C/c1ccc2c(c1)OCO2
d O=C(NCc1cccs1)c1cccnc1Cl
Answer: b. O=C(Nc1ccc(NC(=O)c2ccco2)nc1)c1ccco1
