Task: Answer the multiple choice question.
Query: Which compound has a 6.150\% 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 additional words.
Options:
(a) O=C(/C=C\Nc1ccc(Cl)cn1)c1ccc(Br)cc1
(b) COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2c2ccc(Br)cn2)cc1
(c) Cc1ccc(CNC(=O)C2CCC(CNc3c(N4CCOCC4)c(=O)c3=O)CC2)cc1
(d) COc1ccc(CCNC(=O)c2cc(S(=O)(=O)N3CCCC3)cn2C)cc1OC
(e) Cc1cc(C)n(CCCNC(=O)c2ccc(C)o2)n1
Answer: b. COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2c2ccc(Br)cn2)cc1
