Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.994\% 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 or b without using any additional words.
Options:
[a] COc1cccc(-n2nnnc2SCC(=O)Nc2ccc(C(C)=O)cc2)c1
[b] CCC(C)NC(=O)CN(c1cc(Cl)cc(Cl)c1)S(C)(=O)=O
Answer: b. CCC(C)NC(=O)CN(c1cc(Cl)cc(Cl)c1)S(C)(=O)=O
