Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.675\% 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) O=C(O)C1CC(=O)N(CCc2c[nH]c3ccccc23)C1
b) Cc1nn(-c2ccccc2)c(C)c1Cc1ccc(O)cc1
Answer: a. O=C(O)C1CC(=O)N(CCc2c[nH]c3ccccc23)C1
