Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.281\% 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 additional words.
Options:
[a] CCOC(=O)c1nc(C)n(-c2cc(Cl)cc(Cl)c2)n1
[b] Cc1onc(-c2ccccc2Cl)c1C(=O)Nc1sc2c(c1C(N)=O)CCC(C)C2
[c] COc1ccc(N(CC(=O)NCc2cccc(OC)c2)S(=O)(=O)c2c(C)noc2C)cc1
Answer: a. CCOC(=O)c1nc(C)n(-c2cc(Cl)cc(Cl)c2)n1
