Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.510\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) Cc1ccc(C(=O)O)cc1-c1ccc(/C=C2\SC(=O)N(CC(=O)Nc3ccccc3)C2=O)o1
(b) O=C1CCCc2c1nc(-c1ccc(F)cc1)n2O
Answer: b. O=C1CCCc2c1nc(-c1ccc(F)cc1)n2O
