Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.493\% 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 additional words.
Options:
a. O=C(CSc1ncn[nH]1)NCCc1ccc(Cl)cc1
b. CCOc1ccc(/C=C/C(=O)Nc2ccc(OC)cc2[N+](=O)[O-])cc1
c. COc1ccc2cc(C(=O)NCCc3ccccc3)[nH]c2c1
Answer: b. CCOc1ccc(/C=C/C(=O)Nc2ccc(OC)cc2[N+](=O)[O-])cc1
