b. Sufi saints
c. Bhattas and Gurusikhs
d. All of the above

Answer 1

Hint:
Guru Grant Sahib is the central religious scripture of Sikhism, seen by Sikhs as the ultimate, sovereign, eternal teacher who follows the line of ten human religious masters. The Adi Granth, his first transmission, was composed by the fifth teacher, Guru Arjan (1564-1606).

Complete step by step solution:
The Adi Granth Sahib was completed on 29 August 1604 [failed verification] and was first installed at Darbar Sahib in Amritsar on 1 September 1604. Baba Buddha was named the first Granthi of the Darbar Sahib. Later, Guru Gobind Singh, the tenth Sikh Guru, added all 115 hymns to Guru Teg Bahadur and one of his hymns to Adi Granth and assigned the text as a replacement. This second transmission is known as the Guru Grant Sahib and is sometimes referred to as the Adi Granth. The text consists of 1,430 angels (pages) and 5894 (replicas).

 It contains the hymns, Shabads, slokas of Guru Nanak Dev, Guru Angad Dev, Guru Amar Das, Guru Ram Das and Guru Teg Bahadur. This also includes the "Bani" Hindu saints such as Ravidas, Ramananda, Kabir, Bhagat Bhikan, and Sheikh Farid.

Hence, the correct answer is option D.

Note:
Whole Guru Granth Sahibs are written in Gurmukhi script which was standardized by Guru Angad in the 16th century. Sikhism is classified as an Indian religion along with Buddhism, Hinduism, and Jainism. The foundation of Sikhism lies in the teachings of Guru Nanak and his successors. Some sources refer to Sikhism as a monotheistic religion while others refer to it as a monistic and panentheistic religion.
