Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.794\% 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 additional words.
Options:
[a] COc1cc2c(cc1OC)C(COc1ccc3c(C)cc(=O)oc3c1)N(C(=O)c1ccco1)CC2
[b] CS(=O)(=O)N(CC(=O)NCc1ccncc1)c1cc(Cl)cc(Cl)c1
[c] COc1cc(CN2CC(=O)N(c3cccc(Cl)c3C)C2=S)cc(OC)c1OC
Answer: a. COc1cc2c(cc1OC)C(COc1ccc3c(C)cc(=O)oc3c1)N(C(=O)c1ccco1)CC2
