Which of the following Sikh Guru Compiled the Adi Granth?
A. Guru Nanak
B. Guru Gobind Singh
C. Guru Arjan dev
D. Guru Har Rai

Hint: The martyrdom of Guru Arjan in Mughal custody was one of the defining, albeit divisive, problems in Sikh history. The execution of Guru Arjan was considered by most Mughal historians as a political case, claiming that the Sikhs had become formidable as a gaggle, and Sikh Gurus were actively involved in the political conflicts in Punjabi.

Complete answer:
Guru Arjan was Guru Ram Das and Bhani's mother's youngest sibling. On April 15, 1579, he was born in Goindwal. Guru Arjan was eventually married in 1579 to Ganga Devi, Krishan Chand's daughter. Arjan had two brothers, Prithi Chand and Mahadev, who were elderly. Guru Ram Das chose Arjan, the youngest, to be the fifth Sikh Guru to succeed him. As in most of the history of the Sikh Guru Successions, his choice of Arjan as successor led to disputes and internal divisions among the Sikhs. This incident gave a perspective to the Sikh tradition. It notes that the execution of the Guru was a neighborhood within the Mughal empire of the ongoing persecution of the Sikhs by Islamic authorities. The Guru was imprisoned in Lahore Fort in 1606 CE, where he was tortured and executed by some accounts, and the method of his death remains unresolved by other accounts.

So, the correct Answer is Option C.

Note: The Adi Granth also called Granth or Granth Sahib, the sacred scripture of Sikhism, a religion of India. It is a collection of hymns of the Sikh gurus and various early and medieval saints of different religions and castes.
