The correct answer is D. Maldharis.
Maldharis are a semi-nomadic pastoral community found in the Kutch and Banaskantha districts of Gujarat. They are traditionally camel herders and have a deep understanding of the desert environment. They are also known for their traditional skills in tracking and gathering intelligence.
In recent years, the security agencies of India have recruited Maldharis to monitor the borders of Gujarat. This is because they have the traditional knowledge and skills that are necessary to track infiltration and gather intelligence in the desert environment.
The other options are incorrect. Raikas are a community of camel herders found in Rajasthan. Puggies are a community of snake charmers found in Gujarat. Agaria are a community of iron smelters found in Madhya Pradesh.
