Task: Answer the multiple-choice question.
Question: Which compound has a -0.338\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: c1ccc(CCNc2ncnc3c2cnn3-c2ccccc2)cc1
b: Cc1sc(-n2c(C)cc(/C=N/n3cnnc3)c2C)c(C#N)c1C
c: COc1ccc(/C=N\N=C(N)N)cc1.O=[N+]([O-])O
d: COc1cc(CN2CCCN(C)CC2)cc([N+](=O)[O-])c1O
e: Cc1cccc(C)c1NC(=O)C(NC=O)c1ccccc1
Answer: b. Cc1sc(-n2c(C)cc(/C=N/n3cnnc3)c2C)c(C#N)c1C
