The _______ decision to merge will significantly impact both companies' stock values.
Which choice completes the text so that it conforms to the conventions of Standard English?
board of directors'
board of director's
board's of directors
boards of directors'
Correct Answer: A
Choice A is the best answer. This question tests apostrophe placement with compound nouns.
- Context clues: The board (as a complete entity) made the decision.
- Meaning: For compound nouns, add the possessive to the last word.
- Verify: "The board of directors' decision" correctly shows possession by the compound noun.
💡 Strategy: For compound nouns, add the possessive apostrophe to the final word of the compound.
Choice B is incorrect because "director's" makes only the last word singular possessive incorrectly. Choice C is incorrect because the apostrophe is placed on the wrong word. Choice D is incorrect because "boards" incorrectly pluralizes the compound structure.
