It is located at 0 degrees latitude and circles the Earth horizontally. It passes through various countries and regions. In the case of the provided options, the equator runs through Africa. Africa is the only region among the given options that is intersected by the equator. It passes through several African countries, such as Kenya, Uganda, the Democratic Republic of the Congo, and Brazil. While options 2, 3, and 4 are incorrect because they do not represent regions through which the equator runs, Africa accurately represents a region along the equator`s path.
