The correct answer is option 1: "It is a scheme for mentoring first generation entrepreneurs."

The Niryat Bandhu Scheme is a government scheme aimed at mentoring and guiding first-generation entrepreneurs in the field of exports. The scheme provides essential assistance and support to individuals or small businesses who are venturing into the export industry for the first time.

Option 2, which states that it is a scheme for crop protection, is incorrect. The Niryat Bandhu Scheme is not focused on protecting crops; it is specifically for mentoring and supporting entrepreneurs in the export sector.

Option 3, which suggests that it is a scheme for the vulnerable section of society, is also incorrect. While the Niryat Bandhu Scheme aims to support small businesses and entrepreneurs, it is not exclusively targeted towards the vulnerable sections of society.

Option 4, which states that it is a scheme for monitoring rural poor, is again incorrect. The Niryat Bandhu Scheme does not have any objectives related to monitoring or addressing issues faced by the rural poor.

Therefore, option 1 is the correct statement about the Niryat Bandhu Scheme.
