Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.058\% 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: CC(=O)NNC(=O)c1ccncc1
b: CCCCNC(=O)/C(=C/c1ccccc1)NC(C)=O
Answer: b. CCCCNC(=O)/C(=C/c1ccccc1)NC(C)=O
