Task: Answer the multiple choice question.
Query: Which compound exhibits a -2.464\% 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] COCCn1c(SCC(=O)Nc2ccc(C(C)=O)cc2)nnc1-c1ccco1
[b] O=C1CC(C(=O)N2CCN(c3ccc(F)cc3)CC2)CN1CCc1ccccc1
[c] O=C(c1cc(Br)c(Br)s1)N1CCN(c2ccccn2)CC1
Answer: b. O=C1CC(C(=O)N2CCN(c3ccc(F)cc3)CC2)CN1CCc1ccccc1
