Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.908\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cc1nn(S(=O)(=O)N2CCOCC2)c(C)c1Br
b C=CCNc1nc(C)c(C(C)=O)cc1C#N
c Cc1cccc(OCc2nc3ccccc3c(=O)n2N)c1
d COc1cc(-n2c(=S)[nH]c3ccccc3c2=O)c(Cl)cc1Cl
e O=C(CSc1nc2ccccc2s1)CSc1nc2ccccc2s1
Answer: b. C=CCNc1nc(C)c(C(C)=O)cc1C#N
