Let's analyze each statement based on Census 2011 provisional figures for Uttar Pradesh: I. It is the fourth largest State of India in area. (Incorrect. In 2011, UP ranked 4th by area, but after the bifurcation of Andhra Pradesh in 2014, it became the 4th largest. At the time of Census 2011, Rajasthan, Madhya Pradesh, and Maharashtra were larger, making UP 4th. So this statement could be considered contextually correct for 2011). Correction: Area-wise in 2011, Rajasthan (1st), Madhya Pradesh (2nd), Maharashtra (3rd), Andhra Pradesh (4th pre-bifurcation). UP was 5th or 4th depending on counting order, but generally not listed as 4th largest above Andhra Pradesh. Rajasthan, MP, MH are definitely larger. UP is 243,290 sq km, while Andhra Pradesh was 275,045 sq km before bifurcation. So UP was 5th. Statement I is incorrect. II. It contributes 16.5 percent of the country's population. (Correct. UP population in 2011 was approx. 199.8 million, India's total was approx. 1210.9 million. higher than the national average. (Incorrect. UP sex ratio in 2011 was 912 females per 1000 males. The national average was 943 females per 1000 males. UP's sex ratio was lower than the national average). IV. Its literacy rate is lower than the national average. (Correct. UP literacy rate in 2011 was literacy rate was lower than the national average). Based on this analysis, statements II and IV are correct.
