Task: Answer the multiple choice question.
Query: Which drug has a 18.879\% 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: Cc1c(Cl)c(C(=O)N2CCCc3ccccc32)nn1C
b: O=C(C1=C[C@H](c2ccccc2)C[C@H](OCc2ccc(CO)cc2)O1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
c: O=C(O)CCCC(=O)Nc1cccc(-c2nc3ccccc3[nH]2)c1
Answer: c. O=C(O)CCCC(=O)Nc1cccc(-c2nc3ccccc3[nH]2)c1
