Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.829\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COCCCNC(=O)/C(C#N)=C/c1c(N2CCN(C)CC2)nc2ccccn2c1=O
b COc1cccc(Sc2cc(N3CCOCC3)nc(-c3ccccc3)n2)c1
Answer: b. COc1cccc(Sc2cc(N3CCOCC3)nc(-c3ccccc3)n2)c1
