How did making Egypt a protectorate fuel
nationalist discontent in Egypt?

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Making Egypt a protectorate fueled nationalist discontent in Egypt because Egyptian people never accepted the intervention of Great Britain in Egyptian affairs, even less than the British came to directly rule Egypt in its territory.

For instance, Nationalists started a revolt in 1879. In 1882, the British troops had to intervene to stop the revolt and to protect the economic and political interests of England in Egypt. And the war started.

The English won the war and restored their rule in Cairo, Egypt.

Egypt declared its independence from England until 1992, although the British left their military until the resolution of the Suez Channel crisis of 1956.
