From north to south in Himalayas, which one of the following is the correct sequence of the given mountain passes ?

The correct latitudinal sequence from north to south for these Himalayan passes is Charding La, Shipki La, and then Muling La. Charding La is located in the Ladakh region (near the Demchok sector), making it the northernmost of the three [t1][t2]. Moving south, Shipki La is situated in the Kinnaur district of Himachal Pradesh at an altitude of 3,930 m, where the Satluj River enters India [c1]. Further south is Muling La, which is located north of Gangotri in the Uttarkashi district of Uttarakhand [c4]. Muling La connects Uttarakhand with Tibet and sits at a higher altitude of approximately 5,669 m [c2][c4]. Therefore, the geographical progression from the trans-Himalayan region of Ladakh through Himachal Pradesh to the Garhwal Himalayas in Uttarakhand confirms the sequence: Charding La (Ladakh) - Shipki La (Himachal Pradesh) - Muling La (Uttarakhand).
