Task: Answer the multiple choice question.
Query: Which compound has a 1.754\% 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) COc1ccc(C2CC(=O)C(C=NCCN3CCN(C(=S)Nc4ccccc4)CC3)=C(O)C2)cc1OC
b) Cc1onc(-c2ccccc2)c1C(=O)N1CCC2(CC1)OCCO2
c) Cc1cc(N)n2ncc(-c3cccc(Br)c3)c2n1
Answer: a. COc1ccc(C2CC(=O)C(C=NCCN3CCN(C(=S)Nc4ccccc4)CC3)=C(O)C2)cc1OC
