Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.553\% 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 other words.
Options:
(a) COc1ccc(NC(=O)NC2(C(=O)N3CCCCCC3)CCCCC2)cc1
(b) Cc1ccsc1C1C(C#N)=C(N)OC2=C1C(=O)CC(C)C2
Answer: a. COc1ccc(NC(=O)NC2(C(=O)N3CCCCCC3)CCCCC2)cc1
