Task: Answer the multiple choice question.
Query: Which drug has a -4.861\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] S=c1nc(NCc2ccc3c(c2)OCO3)c2ccccc2[nH]1
[b] COc1nc(N/N=C/c2cccc(Br)c2)nc(N2CCCCC2)n1
[c] CCOC(=O)c1cc(-c2ccccc2)nn1CC1CC(c2cccnc2)=NO1
Answer: b. COc1nc(N/N=C/c2cccc(Br)c2)nc(N2CCCCC2)n1
