Answer: BEES'
Explanation: The right spelling to indicate possession when the noun is plural and it ends in "s" is to just add the apostrophe at the end of the word.
In the example the possessive 's is used to show that the hive belongs to the bees, so, as the word "bees" ends in "s" you only have to write the (')
The second option would be correct if the word was singular. Option 3 is incorrectly written and option 4 is not a possessive form.
