Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.997\% 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] O=c1nc2sc3ccccc3n2c(=O)n1-c1cccc(Cl)c1
[b] CCOC(=O)N1CCN(CC(=O)Nc2ccc(OC)cc2)CC1
[c] CNC(=O)c1cc(S(=O)(=O)NCc2ccncc2)ccc1OC
Answer: a. O=c1nc2sc3ccccc3n2c(=O)n1-c1cccc(Cl)c1
