The correct format for the salutation of a letter that uses open punctuation is option D: Dear Mr. Rodrigues.

To determine the correct format for the salutation of a letter that uses open punctuation, we first need to understand what open punctuation is. Open punctuation is a style of punctuation where no punctuation marks, such as commas or colons, are used after the salutation or the closing of a letter.

In this case, we are looking for the correct format for the salutation. The salutation is the part of the letter that greets the recipient. It is a way to address the person you are writing to formally or informally.

Let's analyze the options:

A. Dear Mr. Joseph Rodrigues,
This option includes a comma after the recipient's name. Since we are looking for the format that uses open punctuation, this option is not correct.

B. Mr. Joseph Rodrigues:
This option uses a colon after the recipient's name. Again, since we are looking for open punctuation, this option is not correct.

C. Dear Mr. Rodrigues:
This option does not include any punctuation after the recipient's name. This aligns with the open punctuation style, making it a suitable choice.

D. Dear Mr. Rodrigues
This option is similar to option C but does not include a colon after the recipient's name. It also aligns with open punctuation.

Based on the explanation above, the correct format for the salutation of a letter that uses open punctuation is D. Dear Mr. Rodrigues.

When using open punctuation in a letter, it is important to omit any unnecessary punctuation marks in the salutation and closing. This style offers a more relaxed and informal approach to letter writing.
