Answer:
Correct answer is: She expanded trade routes and brought strength and wealth to Egypt.
Step-by-step explanation:
First option is not correct as she has ruled during the New Kingdom.
Second option is correct as her reign is known as the period of peace and great trade contacts that were mostly established towards the south. She was actually the first female pharaoh.
Third option is not correct as the social hierarchy in Egypt was established during the first pharaohs and was not easily to be changed.
Fourth option is also not correct as even the first pharaoh had their tombs in a pyramid. That includes the pharaoh from the Old Kingdom, including Cheops, but also some that came before.
