Task: Answer the multiple choice question.
Question: Which drug has a 17.137\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a c1ccc(CCn2cnc3ccccc32)cc1
b C=CCn1cc(-c2ccccc2)cc(C#N)c1=O
c COc1ccc(-c2ccc3c(c2)S(=O)(=O)c2cccc(C(=O)NC[C@@H]4CCCO4)c2C3=O)cc1OC
Answer: b. C=CCn1cc(-c2ccccc2)cc(C#N)c1=O
