Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.428% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cc1ccc(C(=O)Nc2ccc([N+](=O)[O-])cn2)o1
b O=C(O)Cc1ccc(NC(=O)c2cnccn2)cc1
c CCOC(=O)Cc1csc(NC(=O)COc2ccc3c(c2)CCC3)n1
d CN1C(=O)C(=O)N(CC(=O)Nc2ccccc2OC(F)F)C1=O
e CCN1C/C(=C/c2sccc2C)c2nc3ccccc3c(C(=O)O)c2C1.Cl
Answer: a. Cc1ccc(C(=O)Nc2ccc([N+](=O)[O-])cn2)o1
