Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 14.140\% 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 other words.
Options:
a: Cc1ccc(-c2noc(CCC(=O)N3CCCC3)n2)cc1
b: CCN(CC)C(=O)CSC(Nc1cccc(F)c1)=C(C#N)C#N
c: COc1ccccc1NC(=O)c1cc2ccc(O)cc2o/c1=N\O
d: Cn1cnnc1SCc1nc(N)nc(Nc2ccccc2)n1
e: O=C1NC(=O)C(CC(=O)N(Cc2ccco2)C2(C(=O)NC3CCCCC3)CCCCC2)N1
Answer: b. CCN(CC)C(=O)CSC(Nc1cccc(F)c1)=C(C#N)C#N
