Task: Answer the multiple choice question.
Query: Which compound has a -1.920\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccc(N2CC(C(=O)NCCc3ccc(Cl)cc3)CC2=O)cc1
b C#CCSc1ncc(S(=O)(=O)c2ccccc2)c(=O)[nH]1
c CN1CCN(c2ccncc2S(=O)(=O)N2CCCCC2)CC1
d CC(C)(C)OC(=O)N[C@@H](/C=C/c1ccccc1)C(=O)OC(C)(C)C
Answer: d. CC(C)(C)OC(=O)N[C@@H](/C=C/c1ccccc1)C(=O)OC(C)(C)C
