Consider the following statements: As per 2001 Census 1. The two States with the lowest sex ratio are Haryana and Punjab. 2. The two States with the lowest population per sq. km of area are Meghalaya and Mizoram. 3. Kerala has both the highest literacy rate and sex ratio. Which of the statements given above is/are correct?

Evaluating statements based on the 2001 Census of India: 1. Statement 1: According to the 2001 Census, the states with the lowest sex ratio (females per 1000 males) were indeed Haryana (861) and Punjab (876), although some Union Territories like Daman & Diu (710) and Dadra & Nagar Haveli (812) were lower. Among states, Haryana and Punjab had the lowest. So, statement 1 is correct. 2. Statement 2: Population density (population per sq. km) depends on population and area. According to the 2001 Census, the state with the lowest population density was Arunachal Pradesh (13), followed by Mizoram (42) and Sikkim (76). Meghalaya (103) was higher than these. Therefore, stating the two lowest are Meghalaya and Mizoram is incorrect. 3. Statement 3: According to the 2001 Census, Kerala had the highest literacy rate (90.86%) among states and also the highest sex ratio (1058). So, statement 3 is correct. Therefore, statements 1 and 3 are correct.
