Task: Answer the multiple choice question.
Query: Which drug has a 9.898\% 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] Cc1nn(CC#N)c(=O)n1-c1ccc(Cl)cc1
[b] CCCCC(=O)NC(Nc1cc(C)ccn1)(C(=O)OCC)C(F)(F)F
Answer: a. Cc1nn(CC#N)c(=O)n1-c1ccc(Cl)cc1
