Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.555\% 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. Cc1ccc(C(NC(=O)NCCCN2CCOCC2)=C(Cl)Cl)cc1F
b. COc1nnc(-c2ccc(C)cc2)c2ccccc12
c. Cc1cccc(-c2nsc(SCC(=O)NCc3ccco3)n2)c1
Answer: b. COc1nnc(-c2ccc(C)cc2)c2ccccc12
