Task: Answer the multiple-choice question.
Query: Which compound exhibits a -0.636\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=c1c(Cl)c(N/N=C/c2ccc(Cl)cc2)cnn1-c1ccccc1
[b] Cn1cc2c(=O)n(/N=C/c3ccccc3)cnc2n1
[c] COc1ccc(CCNC(=O)Cn2cccc2C(=O)c2ccccc2)cc1OC
Answer: b. Cn1cc2c(=O)n(/N=C/c3ccccc3)cnc2n1
