[amp_mcq option1=”You must” option2=”remember me” option3=”to post this letter” option4=”No error” correct=”option4″]
The correct answer is: D. No error
The sentence “You must remember me to post this letter” is grammatically correct. The word “to” is used in this sentence as an infinitive marker, which indicates that the verb “post” is in its infinitive form. The infinitive form of a verb is used after certain verbs, such as “remember” and “ask.”
The sentence could also be written as “You must remember to post this letter.” However, the use of the word “to” is optional in this case.
