The correct answer is 4.
Veld, or veldt, is a type of wide open rural landscape in Southern Africa. Particularly, it is a flatter area covered in grass or low scrub, especially in the countries of South Africa, Lesotho, Swaziland, Zimbabwe, Botswana, and Namibia. A certain sub-tropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. The spelling "veldt" is anachronistic. Wildfires are common in the veld and are referred to as "veld fires".
