Sagot :
The correct answer would be B because it has a , after Dear Jamal.
Option A needs a comma after Grandpa not a period. Option B is the only accurate sentence as far as I am concerned. It has a comma after Jamal. Options C. (I'm laughing right now) no need of a question mark after Ann. It is not a question. D. No need of a exclamation mark after Ted. Makes no sense.
