The Congress policy of `Pray and Petition` refers to the early moderate phase of the Indian National Congress (1885-1905) that believed in peaceful protests and sending petitions to the British Government to bring about political reforms.

Option 1: Aurobindo Ghosh was a prominent leader and part of the extremist faction within the Congress, however, it was not directly under his guidance that the policy of `Pray and Petition` ended.

Option 2: Bal Gangadhar Tilak, also known as Lokmanya Tilak, played a significant role in transitioning the Congress from the moderate phase to the more aggressive extremist phase. He was one of the first leaders to advocate for `Swaraj` (Self-rule), and encouraged more direct methods of protests. Thus, it was under his guidance that the `Pray and Petition` policy of Congress came to an end.

Option 3: Lala Lajpat Rai was also a key leader during this period, but his prominent activities happened post this transition in Congress` policy.

Option 4: Mahatma Gandhi in fact followed the approach of non-aggressive, non-violent protest which does not fit within the shift away from the `Pray and Petition` policy
