Task: Answer the multiple choice question.
Query: Which compound has a 13.156\% 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] COc1cnn(-c2cccc(C(F)(F)F)c2)c(=O)c1Cl
[b] COc1ccc(-c2nnc(NC(=O)C(C)C)s2)c(OC)c1
[c] CCCCC(c1nnnn1CCOC)N1CCN(Cc2ccccc2)CC1.Cl
[d] Cc1c(C(=O)NCCN(C)C)oc2ccc(S(=O)(=O)N3CCCC3)cc12
[e] O=C(/C=C/c1ccccc1)NCCCNC(=O)/C=C/c1ccccc1
Answer: a. COc1cnn(-c2cccc(C(F)(F)F)c2)c(=O)c1Cl
