खालीलपैकी कोणते विधान/विधाने अयोग्य आहे/आहेत ?
अ. अंतर्गत कर्जामुळे विषमतेत वाढ होत नाही.
ब. परिणामकारक कर्ज व्यवस्थापनाकरिता शासकीय रोख्यांसाठी कार्यक्षम बाजारपेठेची आवश्यकता नसते.
क. सार्वजनिक कर्ज हा शासनाच्या महसुलाचा महत्त्वाचा स्रोत नाही.

The correct answer is Option C (a, b and c).

Key Points:
• Evaluating all three statements critically:
• Statement a is incorrect: Internal public debt DOES exacerbate income inequality. Government bonds are predominantly bought by wealthy individuals and financial institutions; servicing this debt transfers tax revenues collected from the general public to bondholders as interest payments, worsening income distribution.
• Statement b is incorrect: Effective public debt management strictly REQUIRES a deep, liquid, and efficient market for government securities (G-Secs) to manage yields, tenure, and borrowing costs.
• Statement c is incorrect: Public debt is indeed a vital and major capital receipt (source of capital funds/revenue) for modern governments to finance developmental expenditures and bridge budget deficits.
• Because statements a, b, and c are all flawed/incorrect, 'a, b and c' is correct.
• Key Takeaway: All three statements are incorrect: internal debt can worsen inequality, debt management requires efficient G-Sec markets, and public debt is a crucial funding source.
