The correct option is (c) 2 and 3 only.
Explanation
The development of Sikhism involved the spiritual lineage of ten Gurus, the compilation of the holy scripture (Guru Granth Sahib), and the militarization of the community through the Khalsa Panth. These events span from the late 15th century to the early 18th century.
Statement 1 is Incorrect:
The compositions of Baba Guru Nanak were not compiled by Guru Tegh Bahadur. Guru Angad (the second Guru) is credited with compiling the compositions of Guru Nanak in a new script known as Gurmukhi. Later, Guru Arjan Dev (the fifth Guru) compiled the Adi Granth in 1604, which included the hymns of the first five Gurus and various Bhakti and Sufi saints.
Statement 2 is Correct:
The compilation of the Guru Granth Sahib was finalized and authenticated by the tenth Guru, Guru Gobind Singh. He added the hymns of his father, Guru Tegh Bahadur (the ninth Guru), to the Adi Granth. Before his death, Guru Gobind Singh declared this text as the eternal Guru of the Sikhs, ending the lineage of human Gurus.
Statement 3 is Correct:
The Khalsa Panth (community of the pure) was instituted by Guru Gobind Singh in 1699 at Anandpur Sahib. This event marked a significant transformation in Sikhism, defining its distinct identity with the introduction of the "Five Ks" and the titles "Singh" for men and "Kaur" for women.
Key Takeaway:
The Adi Granth was compiled by Guru Arjan Dev (1604), while the final version, the Guru Granth Sahib, was authenticated by Guru Gobind Singh, who also founded the Khalsa Panth in 1699.
