The city of Kartarpur holds immense religious significance, primarily associated with Baba Guru Nanak, the founder of Sikhism. It is believed that Guru Nanak spent the last 18 years of his life in Kartarpur, establishing the first Sikh commune and compiling the sacred hymns that form the Guru Granth Sahib. The Kartarpur Corridor, connecting Dera Baba Nanak in India to the Gurdwara Darbar Sahib in Kartarpur, allows Sikh pilgrims to visit this holy site.
Options 'Amar Singh' and 'Dalbir Singh' are incorrect. These names do not hold the same foundational religious significance or direct historical connection to the establishment and spiritual importance of Kartarpur as Baba Guru Nanak does. His presence and teachings are central to Kartarpur's identity.
