Task: Answer the multiple choice question.
Question: Which drug has a 4.455\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) CC(c1cccnc1)N(C(=O)Nc1ccccc1)C1CCCCC1
b.) CCOC(=O)c1cc(OC(=O)c2ccccc2)n(-c2ccccc2)n1
c.) O=C(Cc1ccccc1)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
d.) COc1cc(C(=O)N/N=C/c2ccc(OC(=O)c3cccc(C)c3)c(OC)c2)ccc1O
Answer: c. O=C(Cc1ccccc1)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
