Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 5.547\% 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.) O=C(Nc1ccc(N2CCOCC2)cc1)c1c(F)cccc1Cl
b.) CCc1c(C2(O)CCCCC2)[nH]c2ccc(C#N)cc12
c.) CCN(c1c(C)n(C)n(-c2ccccc2)c1=O)S(C)(=O)=O
Answer: b. CCc1c(C2(O)CCCCC2)[nH]c2ccc(C#N)cc12
