Hazrat Ume Salma RA advised to prophet PBUH on which event

The correct answer is Suleh Hudaibia. Hazrat Ume Salma RA advised the Prophet Muhammad (PBUH) during the Treaty of Hudaybiyyah (Suleh Hudaibia) in 628 CE. When the Prophet's companions hesitated to follow his instructions after the treaty was signed, Ume Salma RA advised him to go out and perform the sacrifice himself. Her wise counsel helped break the deadlock and demonstrated the importance of practical leadership. The Conquest of Makkah, Ghazwa Badar, and the unfortunate event of the Prophet's illness are not associated with this advice. Therefore, Suleh Hudaibia is the correct event.
