Problem statement: Answer the multiple choice question.
Query: Which drug has a 12.780\% 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] C=CCn1c(C(O)c2ccccc2)nc2ccccc21
[b] Oc1ccccc1C1=NN(c2ccccc2)C(c2ccc(F)cc2)C1
Answer: a. C=CCn1c(C(O)c2ccccc2)nc2ccccc21
