Final Answer:
Guru Gobind Singh Ji's Pathans left him at a very critical point in the Battle of Chamkaur.
Thus the correct option is (B).
Step-by-step explanation:
The Battle of Chamkaur, which took place in December 1705, was a pivotal moment in Sikh history. Guru Gobind Singh Ji, the tenth Sikh Guru, found himself besieged by the Mughal forces along with a small band of his followers, including his two elder sons, Sahibzada Ajit Singh and Sahibzada Jujhar Singh. In the midst of the intense and dire circumstances, Guru Gobind Singh Ji's Pathans, who had previously been in his service, left him when the situation became critically challenging.
The desertion by Guru Gobind Singh Ji's Pathans at such a crucial juncture added to the difficulty faced by the outnumbered Sikhs in the Battle of Chamkaur. Despite the challenging odds, Guru Gobind Singh Ji and his devoted followers displayed extraordinary valor and resilience during the battle. The eventual martyrdom of the Guru's two elder sons in the course of the conflict further elevated the significance of Chamkaur in Sikh history, symbolizing the supreme sacrifice made in defense of principles and justice.
The Battle of Chamkaur is remembered not only for the military confrontation but also for the spiritual and moral fortitude displayed by Guru Gobind Singh Ji and his followers. The betrayal by Guru Gobind Singh Ji's Pathans stands as a poignant episode within this larger narrative, highlighting the testing times faced by the Sikh community during this historic event.
Thus the correct option is (B).
