Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.385\% 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) CCCCOc1cc(C(=O)NCCN(CC)CC)c2ccccc2n1
b) Cc1c(NC(=O)CSc2ncccn2)c(=O)n(-c2ccccc2)n1C
c) CN1C=CC2=C(C#N)C(N)C(C#N)(C#N)C(c3ccccc3)C2C1
d) Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CCN(c4cccc(C(F)(F)F)c4)CC3)ccc21
e) NC(N)=NC(N)=Nc1ccc2ccccc2c1
Answer: e. NC(N)=NC(N)=Nc1ccc2ccccc2c1
