Task: Answer the multiple-choice question.
Query: Which compound exhibits a 9.876\% 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: COc1ccc(/C=C/C(=O)Oc2ccc(/C=N/NC(=O)c3ccccc3)cc2)cc1OC
b: COc1ccc(CCNC(=O)c2nnc(Cc3ccc(Cl)cc3)o2)cc1OC
c: Cc1nc(-c2ccc(Br)cc2)ccc1C(=O)O
Answer: b. COc1ccc(CCNC(=O)c2nnc(Cc3ccc(Cl)cc3)o2)cc1OC
