Choose the correct answer from the codes given below:

• Statement 1: Tamil Nadu indeed recorded the maximum increase in the urbanization ratio during the 1961-2001 period, which is true. • Statement 2: The average size of an urbanized center in India is indeed 45,000, which is also true. • Statement 3: The largest number of urbanized centers do not come in the fourth category. This statement is incorrect as the largest number of urbanized centers is typically found in the fifth category (population size between 5,000 to 9,999). • Statement 4: The statement regarding cities in the fifth and sixth categories is false because they do not collectively house more than 5% of the total urban population of the country. Thus, the correct combination is 1 and 2.
