Task: Answer the multiple choice question.
Question: Which compound exhibits a -19.054% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COc1ccc(OC)c(CN2CCN(S(=O)(=O)c3ccccc3)CC2)c1
b. O=C1C[C@@H](c2ccccc2)Oc2cc(O)cc(O)c21
c. COC(=O)C1=C(C(=O)OC)[C@@H]2N(C)c3ccc(OC)cc3[C@@]23C[C@@H](C(=O)OC)N(C(=O)NCCBr)C3=N1
Answer: b. O=C1C[C@@H](c2ccccc2)Oc2cc(O)cc(O)c21
