Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.435\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) Cc1ccc(NC(C(N)=O)c2c(C)[nH]c(=O)[nH]c2=O)cc1
b) CCn1c(=O)n(CC)c2cc(S(=O)(=O)Nc3cc(C)cc(C)c3C#N)ccc21
Answer: b. CCn1c(=O)n(CC)c2cc(S(=O)(=O)Nc3cc(C)cc(C)c3C#N)ccc21
