Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.673\% 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(NCc1ccc(F)cc1)c1noc2c1CCCC2
b C=CCN1C(=O)c2ccc(C(=O)N(CC)CC(=O)Nc3ccc(OC)cc3)cc2C1=O
Answer: a. O=C(NCc1ccc(F)cc1)c1noc2c1CCCC2
