Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.414% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(Nc1ccc(F)cc1)C(=O)c1c(O)[nH]c2ccc([N+](=O)[O-])cc12
b Cc1nc2ccccc2c(=O)n1/N=C/c1ccccc1O
c C/C(=N\NC(=S)NCc1ccccc1)c1ccc2c(c1)OCCO2
d O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)c1ccc(NCCCN2CCOCC2)c([N+](=O)[O-])c1
Answer: a. O=C(Nc1ccc(F)cc1)C(=O)c1c(O)[nH]c2ccc([N+](=O)[O-])cc12
