Task: Answer the multiple choice question.
Query: Which compound exhibits a 19.044\% 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.) O=C(NCc1cccnc1)C12CC3CC(CC(Cl)(C3)C1)C2
b.) CCN(CC)CCCNC(=O)c1cc2c(=O)[nH]c3ccc(C)cc3c2s1
c.) O=C(/C=C/c1cccs1)Nc1ccc(N2CCOCC2)c(S(=O)(=O)Nc2ccccc2Cl)c1
Answer: a. O=C(NCc1cccnc1)C12CC3CC(CC(Cl)(C3)C1)C2
