Binding of a Molecule from a Pathogen to a Receptor $\kappa$

Binding of a molecule from a pathogen to a receptor initiates a signal transduction pathway. Which is the correct order of events in this pathway?

A) Phosphorylation of NF- $\kappa$ B, binding of NF- $\kappa$ B to the promoter, activation of toll receptor, transcription of defense genes
B) Binding of NF- $\kappa$ B to the promoter, phosphorylation of NF- $\kappa$ B, activation of toll receptor, transcription of defense genes
C) Activation of toll receptor, phosphorylation of NF- $\kappa$ B, binding of NF- $\kappa$ B to the promoter, transcription of defense genes
D) Activation of toll receptor, binding of NF- $\kappa$ B to the promoter, phosphorylation of NF- $\kappa$ B, transcription of defense genes
E) Binding of NF- $\kappa$ B to the promoter, activation of toll receptor, transcription of defense genes, phosphorylation of NF- $\kappa$ B
