Task: Answer the multiple choice question.
Query: Which drug has a -18.790\% 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) COc1ccc(-c2nnc(SCc3nnc(-c4ccccc4)o3)n2C)cc1OC
b) Cc1nc2scc(-c3ccccc3)c2c(=O)o1
c) CNC(=O)COc1ccc(Nc2nnc(C)c3ccccc23)cc1.Cl
Answer: a. COc1ccc(-c2nnc(SCc3nnc(-c4ccccc4)o3)n2C)cc1OC
