Task: Answer the multiple choice question.
Query: Which drug has a 5.490\% 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 CNC(=S)N1CCC(NC(=O)c2ccco2)CC1
b O=C(COC(=O)C1C2CC3OC(=O)C1C3C2)Nc1ccc(F)cc1
c CN(C)c1ccnc(Oc2ccc(C(C)(C)C)cc2)c1C#N
d O=C(CC(Cc1ccccc1)C(=O)O)NCCc1ccc2c(c1)OCO2
Answer: a. CNC(=S)N1CCC(NC(=O)c2ccco2)CC1
