Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.539\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(NCCN1C(=O)S/C(=C\c2cccnc2)C1=O)C1=NN(c2ccccc2)C(=O)CC1
b.) CCN(CC(=O)Nc1ccc(NC(C)=O)cc1)C(=O)CSC(c1ccccc1)c1ccccc1
c.) Cc1ccccc1-c1nnc(NC(=O)c2ccc(N3C(=O)CCC3=O)cc2)s1
d.) Cn1c(=O)c([N+](=O)[O-])c(NCc2ccccc2Cl)c2ccccc21
Answer: c. Cc1ccccc1-c1nnc(NC(=O)c2ccc(N3C(=O)CCC3=O)cc2)s1
