Task: Answer the multiple-choice question.
Question: Which drug has a 0.836\% 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: NC(=O)COC(=O)c1cccc2c1-c1ccccc1C2=O
b: Cc1ccc(C(=O)N(c2ccccc2)C2CC(C)N(C(=O)c3ccco3)c3ccccc32)cc1
c: CCOC(=O)c1cnn2c(C(F)(F)F)cc(-c3ccco3)nc12
d: COc1cccc(OC)c1C(=O)Nc1cccc(NC(=O)c2cccs2)c1
Answer: a. NC(=O)COC(=O)c1cccc2c1-c1ccccc1C2=O
