Task: Answer the multiple choice question.
Question: Which compound has a -1.564\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCCN(C(=O)CCNC(=O)Cn1cnc2ccccc2c1=O)c1cccc(C)c1
b: Cc1ccc2c(c1)C1CN(C)CCC1N2C(=O)/C=C/c1ccc2c(c1)OCO2
Answer: b. Cc1ccc2c(c1)C1CN(C)CCC1N2C(=O)/C=C/c1ccc2c(c1)OCO2
