Problem statement: Answer the multiple-choice question.
Query: Which drug has a -0.387\% 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. CCCCC(=O)Nc1cccc(NC(=O)c2ccc(Br)o2)c1
b. COC(=O)/C(C#N)=C/c1ccc(-c2ccc(S(N)(=O)=O)cc2)o1
Answer: a. CCCCC(=O)Nc1cccc(NC(=O)c2ccc(Br)o2)c1
