Which sentence shows plural possession?

• A. Elephants tusks are made of ivory.
• B. Elephants' tusks are made of ivory.
• C. Elephants tusks are made of ivory.
• D. Elephants tusk are made of ivory.

Answer: (C)

Plurals possession is shown by adding an apostrophe after the s in a plural noun. For elephants, which is already plural, you mark ownership with elephants' (apostrophe after the s) and then the possessed noun tusks. So the correct sentence is Elephants' tusks are made of ivory, because it clearly shows that the tusks belong to elephants and agrees with the plural subject. The other sentences miss the possessive marker or mix up singular/plural: lacking the apostrophe does not indicate possession, and using tusk (singular) with a plural subject creates a mismatch.
