Task: Answer the multiple-choice question.
Question: Which drug exhibits a 22.411\% 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 other words.
Options:
a. COc1ccc(-c2coc3cc(OC)cc(O)c3c2=O)cc1
b. CC1(C)CC(=O)C(N=Nc2cc3c(cc2[N+](=O)[O-])OCCO3)=C(O)C1
c. Cc1oc(-c2ccccc2F)nc1CS(=O)CC(=O)NC1CCCC1
Answer: a. COc1ccc(-c2coc3cc(OC)cc(O)c3c2=O)cc1
