The correct option is A Vacuum
Air is present everywhere on earth's surface except vacuum. Vacuum is defined as a space void of matter that is an ideal vacuum space will have no matter , not even air in it. Ideally it is not possible to create a vacuum space on earth but scientists from NASA and other such organizations have been successful in creating sophisticated spaces that have pressure as low as 10-15 Pa in order to conduct experiments that require vacuum space . Apart from vacuum air is present in mountains, valleys, cities, water bodies (in dissolved form). It is one of the most important component required for the existence of life on earth, so practically air is present at all the places on the earth, where life exists.
