Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.667\% 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 CC(NC(=O)COc1cccc(Br)c1)C(=O)O
b O=S1(=O)CC(O)C(NCc2ccco2)C1
c O=C(N/N=C/c1c[nH]c2ccc(Br)cc12)c1ccc2c(c1)OCO2
d CCOC(=O)/C(C#N)=C/c1ccc(OCC(=O)Nc2ccc(OC)cc2)c(OC)c1
Answer: b. O=S1(=O)CC(O)C(NCc2ccco2)C1
