Choose the sentence with the correct possessive form.

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

Answer: (C)

Forming possessions for a single owner means adding 's to the owner’s noun. Since one dog owns one bone, that owner becomes the dog, giving the possessive form dog’s. The thing owned stays in its singular form if there’s only one item, so bone remains singular. With that in mind, The dog's bone is buried in the yard is correct because it properly shows that one dog owns one bone and the bone is buried in the yard, with the verb agreeing to the singular subject bone.

Other structures misalign ownership or number. Using dog bones treats the phrase as a plural noun without showing ownership, and would pair with are, not is. Using dogs' bone suggests multiple dogs share a single bone, which is awkward for this context. And dog bones with is again mismatches number and ownership.
