Task: Answer the multiple-choice question.
Question: Which compound exhibits a 13.045\% 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) O=C(Nc1cccc(N=Cc2cc(Br)cc(Br)c2O)c1)c1ccco1
(b) COc1ccc(-n2c(=O)[nH]c3cc(C(=O)NCCc4ccc(OC)c(OC)c4)ccc3c2=O)c(OC)c1
(c) O=C(NC1CC1)C1CCN(C2CCN(C(=O)c3ccc4cccc(F)c4n3)CC2)CC1
Answer: a. O=C(Nc1cccc(N=Cc2cc(Br)cc(Br)c2O)c1)c1ccco1
