Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.911\% 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.) C[C@H](NCCc1ccc(O)cc1)[C@H](O)c1ccc(O)cc1.Cl
b.) O=C(CN1C(=O)CSC1=O)NC1CCCCC1
c.) O=C(CCc1nnc2ccc(NCc3ccco3)nn12)N1CCCCC1
d.) O=C(Nc1ccccc1)c1ccccc1OCC(O)CN1C(=O)c2ccccc2S1(=O)=O
e.) C=CCc1cccc2cc(C(=O)N3CCN(c4ccccn4)CC3)c(=O)oc12
Answer: a. C[C@H](NCCc1ccc(O)cc1)[C@H](O)c1ccc(O)cc1.Cl
