The average elevation of Tibetan Plateau above sea level is

Standard geographical sources report the Tibetan (Qinghai–Tibetan) Plateau as exceptionally high, with mean elevations commonly cited between about 4,000 m and 4,500 m above sea level. A school-level geography text specifies an average altitude of about 4,500 m (4.5 km) for the plateau [1], and a scientific review also describes the modern plateau as averaging in excess of 4,500 m above mean sea level [2]. Given the MCQ choices (2, 3, 4, 5 km), the best available match is 4 km (option 3) because major references consistently place the plateau’s mean elevation in the 4,000–4,500 m range, making 4 km the closest provided option.
