Which type of universities are recognized for eligibility?

The correct choice is universities recognized by Indian legislation or UGC. This is significant because the UGC, or University Grants Commission, is the primary regulatory body overseeing higher education in India. It establishes standards for university degrees, ensuring that institutions meet specific criteria regarding faculty qualifications, infrastructure, curriculum, and student support services. Degrees from universities that are recognized by the UGC or Indian legislation are considered valid and are widely accepted for employment and further studies in India.

In contrast, internationally accredited universities may have good standing in other countries but aren't automatically recognized under Indian law unless recognized by the UGC. A large student population does not guarantee the quality or recognition of a university; some large institutions may not meet the necessary standards. Lastly, private universities can vary significantly in terms of accreditation and recognition; not all of them are recognized by Indian legislation or UGC, which could potentially render their degrees invalid within the country. Thus, only those universities that are officially recognized by the relevant Indian authorities can ensure eligibility for recruitment processes like those conducted by BHEL.
