Which of the Following Represents the Correct Order of Events $\rightarrow$

Which of the following represents the correct order of events in ethylene signal transduction?

A) Ethylene is produced $\rightarrow$ ethylene binds to its receptor protein $\rightarrow$ cytoplasmic steps are initiated $\rightarrow$ transcription factor is activated
B) Ethylene is produced $\rightarrow$ cytoplasmic steps are initiated $\rightarrow$ transcription factor is activated $\rightarrow$ ethylene binds to its receptor protein
C) Ethylene binds to its receptor protein $\rightarrow$ cytoplasmic steps are initiated $\rightarrow$ transcription factor is activated $\rightarrow$ ethylene is produced
D) Ethylene binds to its receptor protein $\rightarrow$ transcription factor is activated $\rightarrow$ ethylene is produced $\rightarrow$ cytoplasmic steps are initiated
E) Cytoplasmic steps are initiated $\rightarrow$ transcription factor is activated $\rightarrow$ ethylene is produced $\rightarrow$ ethylene binds to its receptor protein
