Task: Answer the multiple-choice question.
Question: Which compound exhibits a -27.225\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) Cn1cccc1CC(=O)N/N=C/c1ccc(C(C)(C)C)cc1
(b) O=C(NC1CCCC1)C(c1ccc(Cl)cc1)N1CCN(C2CCCCC2)CC1
(c) O=C(NCCCN1CCN(c2cccc(Cl)c2)CC1)c1ccc(N2CCCC2=O)cc1
Answer: b. O=C(NC1CCCC1)C(c1ccc(Cl)cc1)N1CCN(C2CCCCC2)CC1
