Task: Answer the multiple-choice question.
Query: Which drug has a 19.609\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COCCOC(=O)C1=C(C)NC(=O)NC1c1c(Cl)nc2c(C)cccn2c1=O
b C=CC(=O)NN(C)c1ncc(C(F)(F)F)cc1Cl
c Cc1cc(=O)cc(C)n1-c1ccccc1N
Answer: b. C=CC(=O)NN(C)c1ncc(C(F)(F)F)cc1Cl
