Both C and D were both male rulers, so we can rule them out.
Next comes Hatshepsut and Cleopatra.
Cleopatra was a co-regent. Even though she was a very strong person of history, Hatshepsut takes the answer.
Hatshepsut ruled for a whopping 20 years, making her considered one of the most successful female Egyptian rulers.
Hope this helps!
