Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.643\% 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(Cn1c(=O)c2cccn2c2ccc(F)cc21)N1CCN(c2ccc(F)cc2)CC1
b.) C=CCOc1cccc(/C=N/NC(=O)C(OC)c2ccccc2)c1
Answer: a. O=C(Cn1c(=O)c2cccn2c2ccc(F)cc21)N1CCN(c2ccc(F)cc2)CC1
