I hope this letter helps you directors of the company help the company

A. I hope this letter helps you directors of the company help the company
'you' inclusion in the middle should be followed with a comma to convey the intended meaning therefore out

B. This letter will hopefully be helpful to you, as directors of the company, so you can help
Will the letter be only helpful to the directors ??? , or the letter is encrypted and the decryption code only lies with the directors , wrong meaning therefore out

C. It is my hope in writing this letter that you, as directors of the company, can help
The meaning is fine therefore let us hang on to it

D. You, as directors of the company, I hope will, after reading this letter, help
letter is the hope of the author , which is not conveyed therefore out

E. It’s hopeful to me, as the author of this letter, that you, as directors of the company, can help
Authoring the letter doesnn't deliver hope , the course of action taken by the director after reading the letter is the hope conveyed by the author , which is not the case of the above sentence therefore out

Therefore IMO C
