Task: Answer the multiple-choice question.
Query: Which drug has a 2.650\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1cc(NC(=O)C2CCCO2)c(C(=O)O)cc1OC
b) O=C(OCC(=O)N1CCc2ccccc21)c1nc(Cl)ccc1Cl
c) O=C(/C=C/c1ccccc1)NC1CCCc2ccccc21
d) O=C(CCCC(=O)N1CCCc2ccccc21)N1CCCc2ccccc21
Answer: b. O=C(OCC(=O)N1CCc2ccccc21)c1nc(Cl)ccc1Cl
