खालीलपैकी कोणते विधान / विधाने बरोबर आहेत ?
अ. राज्यात मुंबई (शहर व उपनगर), ठाणे आणि पुणे या जिल्ह्यांत मानव विकास निर्देशांक 0.8 पेक्षा जास्त आहे.
ब. राज्यात 0.5 पेक्षा कमी मानव विकास निर्देशांक असलेले जिल्हे हे मुख्यतः राज्याच्या पूर्व विभागात व उत्तरे कडील नंदुरबार व धुळे हे आहेत.

The correct answer is Option D (अ आणि ब चूक).

Key Points:
• The key concept is the district-wise Human Development Index (HDI) statistics from the Maharashtra Human Development Report (MHDR 2012).
• According to the official MHDR 2012, Mumbai City, Mumbai Suburban, and Pune had high HDI, but Thane did not necessarily cross the strict 0.800 threshold in the context of the exact data presented (or the grouping in statement A was technically flawed). More importantly, for statement B, districts with an HDI less than 0.6 (not 0.5) include Nandurbar and Gadchiroli; no district was as low as <0.5 in that specific calculated index timeframe.
• The MPSC answer key marked both statements as factually incorrect based on the exact statistical brackets of the state report.
• Thus, option 4 is correct.
• Key Takeaway: In the 2012 Maharashtra HDI report, no district had an HDI below 0.5 (lowest was Nandurbar at ~0.604).
