Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.055\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1cccc2c1[C@@H]1CN(CCCCn3c(=O)[nH]c4c(sc5ncc(-c6ccccc6)nc54)c3=O)C[C@@H]1CO2.Cl
(b) c1ccc2[nH]c(SCc3ccc(-c4nnco4)cc3)nc2c1
