The correct options are
B Col. Pottinger formed a treaty with the Amirs of Sindh.
D The Maharaja was prevented from getting Shikarpur.
Maharaja Ranjit Singh was disappointed when the then British Governor-General sent Col. Pottinger to form a treaty with the Amirs of Sindh. Lord Auckland talked the Maharaja into not attacking the Mazari tribe again. As a result, the Maharaja could neither get Shikarpur nor his annual tax. This greatly strained his relations with the British.
