Final answer:
The correct answer is B. Jones's.
Step-by-step explanation:
The correct answer is B. Jones's.
In this sentence, the word 'Jones's' is used to show possession, indicating that the Christmas card belongs to a person named Jones. The apostrophe and the letter 's' are added to the end of the word 'Jones' to indicate possession. This is called the possessive form.
For example, if the Jones family sent the Christmas card, you would say 'The Jones's Christmas card...' indicating that the Christmas card belongs to the Jones family.
The correct answer to the question is "The Joneses' Christmas card was great this year." When you are referring to something belonging to a family with the surname Jones, you make the name plural by adding an -es to make Joneses. Since you are talking about their Christmas card, you show possession by adding an apostrophe at the end of Joneses to become Joneses'.
