Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.750\% human ether-à-go-go related gene (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) CCCCN1C(=O)C(O)=C(C(C)=O)C1c1ccccc1
(b) COc1ccc(NC(=O)c2sc3ncn(CC(=O)N4CCCCC4)c(=O)c3c2C)cc1OC
Answer: a. CCCCN1C(=O)C(O)=C(C(C)=O)C1c1ccccc1
