Explanation

Cocoa (Theobroma cacao) is a tropical plantation crop native to the Amazon basin that thrives in hot, rainy equatorial climates within 10 to 20 degrees of the equator. Today, West Africa dominates the global cocoa bean market, with the African continent supplying roughly 60% of total worldwide production, heavily concentrated in two adjacent nations.

* Option (a) — Incorrect: Algeria and Morocco are situated in North Africa, dominated by arid Saharan and Mediterranean climates, which cannot sustain tropical, moisture-intensive cocoa cultivation.

* Option (b) — Incorrect: Botswana and Namibia are located in Southern Africa, largely covered by the Kalahari and Namib deserts with semi-arid to hyper-arid conditions unsuitable for cocoa growing.

* Option (c) — Correct: Côte d’Ivoire (Ivory Coast) and Ghana are unequivocally the world’s two largest cocoa producers. Côte d’Ivoire ranks first globally, contributing over 40% of the worldwide supply (~2.2 million metric tons), while neighboring Ghana ranks second, accounting for around 15–20% (~1.1 million metric tons). Together, they produce nearly 60% of the entire world’s cocoa harvest.

* Option (d) — Incorrect: Madagascar and Mozambique are situated in Southeastern Africa; while Madagascar produces high-quality aromatic fine/flavour cocoa, its production volume is negligible compared to the massive commercial yields of West Africa.

Therefore, Côte d’Ivoire and Ghana are the two largest cocoa producers in the world.

Hence, Option (c) is the correct answer.
