Task: Answer the multiple choice question.
Question: Which compound exhibits a -2.307\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCCNS(=O)(=O)c1ccc(OCC(=O)N(C)Cc2ccccc2)cc1
b) CCOC(=O)c1[nH]c(C)c(C(=O)N2CCN(C(=O)OCC)CC2)c1CC
c) O=c1cc(CSc2nc3cc(Cl)ccc3o2)nc2sccn12
d) O=C(Cn1nc(-c2ccccc2)ccc1=O)Nc1ccc(N2CCN(C(=O)c3ccccc3)CC2)cc1
Answer: d. O=C(Cn1nc(-c2ccccc2)ccc1=O)Nc1ccc(N2CCN(C(=O)c3ccccc3)CC2)cc1
