Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -0.068\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(NCCNC(=O)c1cnccn1)c1ccc(Cl)cc1
(b) O=C(CN1C(=O)C2C3CC(C(Br)C3Br)C2C1=O)N1CCN(Cc2ccccc2)CC1
(c) CCn1c(COC(=O)CNC(=O)c2ccccc2)nc2cc(S(=O)(=O)N(C)C)ccc21
(d) COc1ccc(C2C(C(=O)c3ccccc3)=C(C)Nc3nc4ccccc4n32)cc1OC
(e) Cc1ccc(C)c(S(=O)(=O)N2CCN(C(=O)c3ccnn3C)CC2)c1
Answer: d. COc1ccc(C2C(C(=O)c3ccccc3)=C(C)Nc3nc4ccccc4n32)cc1OC
