Correct option is C
Option (c) contains an error.
Explanation: The phrase "with the discovery bone ornaments" is incorrect. It should be "with the discovery
of bone ornaments" because the preposition "of" is required to indicate the object of the discovery.
Grammatical rule used: Use "of" to indicate the object or result of an action (in this case, the discovery).
Example:
Incorrect: The invention
discovery cars.
Correct: The invention
of cars.
