Final answer:
The correct answer is option b) Thebes.
Step-by-step explanation:
During the Amarna Period, Pharaoh Akhenaten, who was likely the father of Tutankhamun, moved the Egyptian capital to the city of Akhetaten, also known as Amarna, as part of his major religious reforms focused on the deity Aten. After Akhenaten's death and a short rule by Pharaoh Smenkhkare, Tutankhamun ascended to the throne. Tutankhamun then decided to shift the religious capital back to its traditional location.
He restored the worship of Amun and moved the religious center from Amarna back to the former capital, Thebes. Thebes was renowned for its significant temples like the ones at Karnak, dedicated to Amun and other gods. This action is seen as an attempt to re-establish the traditional religious order that had been disrupted during his father's reign.
