Mr. ________ profit-and-loss report is due tomorrow.

a. Jones’s
b. Jones’
c. Joneses’
d. Jones

Right. B.

Some sources would vote for a. I believe it depends upon which expert you consult and how s/he pronounces the word.

The correct answer is:

a. Jones's

To determine the correct option for completing the sentence, we need to understand the rules of forming possessive nouns for names ending in "s."

When a singular name ends in "s," the possessive form can be shown by adding an apostrophe and an "s" ('s). For example, "Chris's car" or "James's book."

For plural names ending in "s," the general rule is to just add an apostrophe ('), without an additional "s." For example, "the Smiths' house" or "the Jones' car."

In this case, we are talking about a singular person named Mr. Jones, so we need to use the singular possessive form.

Therefore, the correct option to complete the sentence would be:

a. Jones's

So, the completed sentence would be:

"Mr. Jones's profit-and-loss report is due tomorrow."
