Concept: This question requires knowledge of the precise year Ismail Pasha lost his position as Khedive of Egypt due to British pressure.
Explanation: Ismail Pasha ascended to power as Khedive of Egypt in 1863.
His large-scale modernisation projects and lavish spending created a serious national debt crisis.
European powers, especially Great Britain, intervened in Egypt's financial management due to these debts.
Britain wanted Ismail Pasha removed because he resisted foreign control over Egypt's finances.
Consequently, Great Britain pressed the Ottoman Sultan to depose him from office.
Ismail Pasha was consequently removed as Khedive of Egypt in 1879.
He was succeeded by his son, Tewfik Pasha, who was more compliant with British interests.
Hence, the correct year of his removal is 1879.
Answer: B. 1879
