Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.834\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) Cc1ccc(-n2c(SCC(=O)N3CC(=O)Nc4ccccc43)nc3ccccc3c2=O)cc1
b.) COc1ccc2[nH]c(=O)c(CN(C)C(=O)c3cccs3)cc2c1
c.) COc1ccc2oc(=O)c(C(=O)OCC(=O)c3ccc([N+](=O)[O-])cc3)cc2c1
d.) Cc1csc(NC(=O)C2CCCCC2)n1
e.) CCOC(=O)c1cnc(SC2CC(=O)N(c3ccccc3)C2=O)nc1N
Answer: c. COc1ccc2oc(=O)c(C(=O)OCC(=O)c3ccc([N+](=O)[O-])cc3)cc2c1
