Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.542\% 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] Cc1cccc(S(=O)(=O)c2c(N)n(/N=C/c3cccnc3)c3nc4ccccc4nc23)c1
[b] CC(=O)c1ccc(-c2ccc(C(=O)N(C)c3c(N)n(Cc4ccccc4)c(=O)[nH]c3=O)o2)cc1
Answer: b. CC(=O)c1ccc(-c2ccc(C(=O)N(C)c3c(N)n(Cc4ccccc4)c(=O)[nH]c3=O)o2)cc1
