Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.552\% 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) O=C(CCCN1C(=O)c2ccccc2C1=O)Nc1c(C(=O)C2CC2)oc2ccccc12
b) Cc1ccc(CNc2nc(N)c([N+](=O)[O-])c(Nc3ccc(F)cc3)n2)cc1
c) COc1ccc(NC(=O)CCNS(=O)(=O)c2cccc3nsnc23)cc1OC
d) CCSc1ncc(C#N)c(=O)[nH]1
e) CCC(C)(C)C1CCc2[nH]nc(C(=O)NC(C)C)c2C1
Answer: b. Cc1ccc(CNc2nc(N)c([N+](=O)[O-])c(Nc3ccc(F)cc3)n2)cc1
