Task: Answer the multiple-choice question.
Query: Which drug exhibits a -7.859\% 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: Cc1c(OCC(=O)NCCCN2CCOCC2)ccc2c3c(c(=O)oc12)CCC3
b: COc1ccc2nc(SCc3cccc(C)c3)nc(C)c2c1
c: CCOc1ccccc1N=Cc1c(O)c2ccccc2oc1=O
Answer: b. COc1ccc2nc(SCc3cccc(C)c3)nc(C)c2c1
