Task: Answer the multiple-choice question.
Question: Which compound exhibits a 3.299\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCN1CCN(CCOc2ccccc2OCc2ccccc2)CC1.O=C(O)C(=O)O
b: O=C(C1=C[C@H](c2ccccc2)C[C@H](OCCCCO)O1)N1CCOCC1
c: O=C(Nc1cccc(Cl)c1)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCCC1
d: O=C(O)CSc1c(-c2cccs2)[nH]c2ccccc12
e: CC(C)CN(C(=O)CCNC(=O)c1ccccc1Cl)C1CCS(=O)(=O)C1
Answer: d. O=C(O)CSc1c(-c2cccs2)[nH]c2ccccc12
