Choose the sentence with the correct possessive form?

• A. The dog's bone is buried in the yard.
• B. The dogs bone is buried in the yard.
• C. The dogs' bone is buried in the yard.
• D. The dog bones is buried in the yard.

Answer: (A)

Forming possessives with apostrophes is the key idea. When the owner is singular, you add 's to the noun to show possession. So the bone that belongs to one dog is written as dog’s bone. That makes the sentence with dog’s bone the correct choice.

The other options break the rule in different ways: missing an apostrophe (dogs bone) fails to show possession; using the plural possessive (dogs’ bone) would imply multiple dogs owning one bone, which isn’t the intended meaning here; and using the plural noun bones with is (dog bones is) creates a subject-verb mismatch.
