Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.116\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(O)C1=C(OCc2ccccc2)C(=O)NCC1
b. Nn1cc(-c2ccccc2)nc1SCC(=O)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
c. O=S(Cc1ccccc1)CC(O)(c1ccc(Cl)cc1)c1ccc(Cl)cc1
Answer: a. O=C(O)C1=C(OCc2ccccc2)C(=O)NCC1
