The National Rural Health Mission aims to reduce Infant Mortality Rate to

30 per 1000 live births by 2012
30 per 1000 live births by 2014
35 per 1000 live births by 2012
35 per 1000 live births by 2014

The correct answer is (b). The National Rural Health Mission (NRHM) aims to reduce the Infant Mortality Rate (IMR) to 30 per 1000 live births by 2014. The IMR is the number of deaths of infants under one year of age per 1000 live births in a given year. It is a key indicator of the health of a population. The NRHM is a government program that was launched in 2005 to improve the health of rural India. The program focuses on providing access to quality healthcare, reducing maternal and child mortality, and improving nutrition. The NRHM has been successful in reducing the IMR in India. In 2005, the IMR was 62 per 1000 live births. By 2014, the IMR had been reduced to 41 per 1000 live births. This is a significant achievement, and it is a testament to the success of the NRHM.

Option (a) is incorrect because the NRHM aims to reduce the IMR to 30 per 1000 live births by 2014, not 2012.

Option (c) is incorrect because the NRHM aims to reduce the IMR to 30 per 1000 live births by 2014, not 35 per 1000 live births.

Option (d) is incorrect because the NRHM aims to reduce the IMR to 30 per 1000 live births by 2014, not 35 per 1000 live births.
