(a) मुंबई, मुंबई उपनगर, पुणे, ठाणे जिल्ह्यात लिंगगुणोत्तर सरासरी 925 पेक्षा कमी आहे.
(b) गडचिरोली व गोंदिया जिल्हयात लिंगगुणोत्तर सरासरी 925 पेक्षा अधिक आहे.

The correct answer is Option D (Neither).

Key Points:
• Maharashtra Demographics - Sex Ratio Analysis (Census 2011):
• State Average: The overall sex ratio of Maharashtra as per Census 2011 is 929 females per 1000 males.
• Urbanized Districts with Low Sex Ratio (<925): Statement (a) is correct. Heavy male-selective migration into industrial urban hubs resulted in very low sex ratios:
• Mumbai City: 832
• Mumbai Suburban: 860
• Thane (undivided): 886
• Pune: 915
• (All four are well below 925).
• Eastern Districts with High Sex Ratio (>925): Statement (b) is correct. Tribally concentrated and agrarian eastern Vidarbha districts recorded high sex ratios:
• Gadchiroli: 982
• Gondia: 999
• (Both are significantly higher than 925).
• Since both statements are factually correct, Neither statement is incorrect (Option 4).
• Key Takeaway: As per Census 2011, Mumbai (832), Thane (886), Pune (915) have sex ratio <925, while Gondia (999) and Gadchiroli (982) have >925.
