The correct answer is D. "editors-in-chief."

Explanation:

The correct term to use in this context is "editors-in-chief" (option D). "Editors-in-chief" is the plural form of the term "editor-in-chief," which refers to the highest-ranking editor in an organization or publication. Since the sentence mentions multiple editors, the correct term to use is the plural form "editors-in-chief."

To arrive at this answer, you can break down the sentence and properly identify the correct usage of the term:

"The _______ will meet tomorrow to discuss some upcoming projects."

In this sentence, we need to fill in the blank with the appropriate term that refers to multiple editors holding the highest rank in an organization. Option A, "editor-in-chiefs," is incorrect because the plural form of "chief" should be "chiefs" and not "chiefs." Similarly, option B, "editor in chiefs," is also incorrect because it does not use the proper pluralization for the term "chief."

Option C, "editors in chief," is incorrect because it places the preposition "in" between "editors" and "chief." The hyphens are missing, which results in an incorrect usage of the term.

Therefore, the correct answer is option D, "editors-in-chief," which properly utilizes the hyphens and pluralization to indicate multiple editors holding the highest ranks in an organization.
