Task: Answer the multiple choice question.
Question: Which compound has a 11.977\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(/C=C/c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
b. O=C1OCC(c2ccccc2)=C1c1ccccc1
c. O=C(COC(=O)CNC(=O)c1ccc(-c2ccccc2)cc1)NCc1ccco1
Answer: b. O=C1OCC(c2ccccc2)=C1c1ccccc1
