Problem statement: Answer the multiple choice question.
Question: Which drug has a -35.281\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCCCN(Cc1cc2cc(OC)ccc2[nH]c1=O)C(=O)c1ccccn1
b: CCn1cc(CN(C)C(=O)/C=C/c2ccc([N+](=O)[O-])cc2)c(C)n1
Answer: b. CCn1cc(CN(C)C(=O)/C=C/c2ccc([N+](=O)[O-])cc2)c(C)n1
