- B
B A D C
Jahandar Shah (1712–13) comes first, then Muhammad Shah Rangeela (1719–48), then Ahmad Shah (1748–54), then Alamgir II (1754–59). That order is B A D C. This option is the official key.

C A B D
C A B D starts with Alamgir II, who is last among the four. This option is therefore wrong.
- D
D B C A
D B C A begins with Ahmad Shah and is scrambled. This option is not the key.
Summary. Official key is (b) B A D C. After Bahadur Shah I, Jahandar Shah had a brief reign, Farrukhsiyar intervened, then Muhammad Shah’s long reign, then Ahmad Shah, then Aziz-ud-Din Alamgir II. The four names in the question therefore run Jahandar, Muhammad Shah, Ahmad Shah, Alamgir II. Only (b) is that chronology.
