Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.680\% 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) CCCc1[nH]nc2c1C(c1ccc(OC(=O)N3CCOCC3)c(OC)c1)C(C#N)=C(N)O2
b) Cc1nn(C)cc1C(C(=O)NC1CCCCC1)N(C(=O)Cc1cccs1)c1ccc(C(C)C)cc1
Answer: a. CCCc1[nH]nc2c1C(c1ccc(OC(=O)N3CCOCC3)c(OC)c1)C(C#N)=C(N)O2
