Task: Answer the multiple choice question.
Query: Which compound exhibits a 24.724\% 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) COC(=O)c1cc(C(=O)c2cc(Br)ccc2O)coc1=N
b) Nn1cnnc1SCC(=O)Nc1ccc2c(c1)OCO2
c) O=C(Cn1nnc(-c2ccccc2F)n1)NCCc1ccccc1
Answer: a. COC(=O)c1cc(C(=O)c2cc(Br)ccc2O)coc1=N
