Read the signature.

Jenny

To include this signature in a formal letter, it should be revised to contain the writer's

A. full first name and middle name.

B. nickname and last name.

C. title and full first name.

D. full first name and last name.

The answer is D. First Full Name and last name of the person.

For formal letters should be formal. Writing our full names is a sign of respect towards the person we are addressing the formal letter to. Formal letters are addressed to your superiors or people with positions in companies or organizations. In the signature above, it is an example of an informal letter wherein a person can use a nickname or just their given name.

D first name and last name are needed
