The correct answer is False.
Step-by-step explanation
Hieroglyphs were a writing system invented by the ancient Egyptians that was used from pre-dynastic times (3300 BC to 3150 BC) to the 4th century (300 AD). Hieroglyphs are the oldest organized writing system in the world. Its main use was to make official inscriptions on the walls of temples and tombs. On the other hand, The Middle Kingdom of Egypt includes a period from the year 2050 a. C. - 1750 a. From the above, it can be concluded that during the Middle Kingdom of Egypt the hieroglyphs were not developed for the first time because they were developed a long time before, about a thousand years before. So the answer is False.
