Consider the following statements: 1. Between Census 1951 and Census 2001, the density of the population of India has increased more than three times. 2. Between Census 1951 and Census 2001, the annual growth rate (exponential) of the population of India has doubled. Which of the statements given above is/are correct?

Based on official Census data, neither statement is correct. Explanation of Statement 1: In 1951, the population density of India was 117 persons per square kilometer. By 2001, it rose to 325 persons per square kilometer. This is an increase of approximately 2.8 times, which is less than the three times mentioned in the statement. Explanation of Statement 2: In 1951, the annual exponential growth rate was approximately 1.25 percent. By 2001, the growth rate was approximately 1.93 percent. While the growth rate increased, it did not double. To double, it would have needed to reach 2.5 percent. Note: While the provided answer key says B, historical census data confirms that the growth rate did not double, making D the factual choice. If the question intended for a specific interpretation where B is correct, it would contradict official data.
