खालील विधाने लक्षात घ्या :
(a) राष्ट्रीय मानवी हक्क आयोगाचे कार्य हे प्रामुख्याने शिफारशींच्या स्वरूपाचे आहे.
(b) शासनाला या आयोगाच्या शिफारशी दुर्लक्षित करता येत नाहीत.
(c) आयोगाचे सदस्य राज्य शासनाच्या पूर्वपरवानगी शिवाय देखील तुरुंगांना भेट देवू शकतात.

The correct answer is Option D (All three).

Key Points:
• Powers and Functions of NHRC:
• Statement (a) is correct: Under Section 18 of the Protection of Human Rights Act, 1993, the recommendations of the Commission are essentially advisory and recommendatory in nature; it has no power to punish violators or enforce awards directly.
• Statement (b) is correct in statutory practice: The concerned government must inform the Commission of the action taken or proposed to be taken on its recommendations within one month; the government cannot simply ignore or shelve them arbitrarily without an accountability response.
• Statement (c) is correct: Under Section 12(c) of the Act, the Commission can visit any jail or other institution under the control of the State Government to study living conditions of inmates. The 2006 Amendment removed the prior requirement of intimation to the State Government, allowing surprise visits without prior intimation.
• Thus, according to the official key, all three statements are correct.
• Key Takeaway: NHRC functions are recommendatory, reports require mandatory government response within one month, and jail visits need no prior intimation.
