Task: Answer the multiple choice question.
Question: Which drug has a -4.537\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CC(C)Sc1nc(O)c(Cc2ccccc2)c(=O)[nH]1
b CN(O)/C=c1/ccc2c(n1)C(=O)C=CC=2
c C/C(=N\NC(=O)Cc1cccn1C)c1ccc([N+](=O)[O-])cc1
Answer: b. CN(O)/C=c1/ccc2c(n1)C(=O)C=CC=2
