Question

You wish to invite a few of your friends over for dinner. Which of the following options is the most appropriate closed for the letter?
a) Yours faithfully,
b) Yours respectfully,
c) Yours,
d) Dear friends,

Answer 1

Hint: First, we have to know that this letter is being addressed to our friends so the tone of the letter is going to be informal. Secondly, we have to select the appropriate closing for the letter and not the opening.

Complete answer:
 Let us use the elimination method to reach the answer to this question.
Since we have to select the appropriate closing for the letter we can eliminate option d because option d is an opening and not a closing.
Thus, option d is the wrong answer.
Option a is a very formal closing. We usually use yours faithfully when we are writing to someone older than us. The person older to us can be our family or can be someone with whom we share a professional relationship.
Option b is also wrong because yours respectfully is a very professional closing and we use it with people with whom we strictly follow a professional relationship. So it is only used in formal letters.
Thus, after eliminating options a, b and d, we can see that option c is left. Option c is "yours". It is the correct answer because "yours" is an informal closing for a letter which we are writing to our friends and loved ones.

 Formal and informal letters have different styles of opening and closing salutations. It would be beneficial to be familiar with them.
