Problem statement: Answer the multiple-choice question.
Query: Which drug has a -2.834\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COc1ccc(C(C(N)=O)c2ncc(C(F)(F)F)cc2Cl)cc1OC
(b) O=C(CN1CCCCC1)Nc1ccc(Br)cc1[N+](=O)[O-]
(c) Cc1cccc(OCc2nc(C#N)c(N3CC(C)CC(C)C3)o2)c1
(d) O=C(O)c1nc(N2CCCCC2)ncc1Cl
(e) CN(C(=O)COC(=O)c1c2c(nc3ccccc13)CCCC2)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: a. COc1ccc(C(C(N)=O)c2ncc(C(F)(F)F)cc2Cl)cc1OC
