CorrectNot quiteAnswer C

Correct answer: C

Laterite forms where high temperature and heavy seasonal rain wash the soluble minerals out of the soil.
What is left behind is rich in iron and aluminium oxides, which gives laterite its red colour and its hardness.
It is poor in nitrogen, lime and organic matter, so it needs heavy manuring before it will farm well.

Worth noting

Weathering of basalt lava produces black soil, not laterite — that is the option worth reading twice.
