Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.796\% 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: COc1ccc(Br)cc1-c1nc(C)c(C(C)=O)n1O
b: CC1(C)OC(=O)N(CCc2ccccc2)C1(C)O
c: CCc1nnc(NC(=O)c2cc3ccccc3oc2=O)s1
Answer: a. COc1ccc(Br)cc1-c1nc(C)c(C(C)=O)n1O
