Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.131% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC1CCN(C(=O)COC(=O)c2n[nH]c3ccccc23)CC1
b: CN(C(=O)c1cnn(C)c1)C12CC3CC(CC(C3)C1)C2
c: CCOC(=O)[C@H](CCc1ccccc1)N[C@@H](C)C(=O)N1CCC[C@@H]1C(=O)O.O=C(O)/C=C\C(=O)O
d: O=C(Nc1ccc(C(=O)N2CCN(c3ccccc3)CC2)cc1)C1=CSCCO1
Answer: c. CCOC(=O)[C@H](CCc1ccccc1)N[C@@H](C)C(=O)N1CCC[C@@H]1C(=O)O.O=C(O)/C=C\C(=O)O
