Task: Answer the multiple choice question.
Question: Which drug has a 9.284\% 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 CSc1nn2c(C(F)(F)F)cc(C(F)(F)F)nc2c1C(=O)O
b COc1ccc(OC)c(C(=O)NC(CC(N)=O)c2ccc(NCCN3CCCC3)c([N+](=O)[O-])c2)c1
Answer: a. CSc1nn2c(C(F)(F)F)cc(C(F)(F)F)nc2c1C(=O)O
