Task: Answer the MCQ question.
Query: Which drug exhibits a 9.630\% 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: C=CCOC(=O)C1=C(C)NC(SCC(N)=O)=C(C#N)C1c1ccc(C)cc1
b: CC(=O)N1c2ccc(S(=O)(=O)NCC3CCC(C(=O)NCc4ccc(C)o4)CC3)cc2CC1C
Answer: a. C=CCOC(=O)C1=C(C)NC(SCC(N)=O)=C(C#N)C1c1ccc(C)cc1
