Task: Answer the multiple choice question.
Query: Which drug has a 8.447\% 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. O=C(NCC1CCCN1S(=O)(=O)c1cccs1)c1ccc(F)c(F)c1
b. CC1=NN(c2ccccc2)C(=O)C1/C=C1/NC(=S)NC1=O
Answer: a. O=C(NCC1CCCN1S(=O)(=O)c1cccs1)c1ccc(F)c(F)c1
