Correct option is C
Given: 4 : 9, 25 : 49, (?), 289 : 361
Logic: The given numbers are the squares of the consecutive prime numbers (starting from 2).
4 : 9; (2) = 4, (3) = 9
25 : 49; (5) = 25, (7) = 49
Similarly, the next prime numbers are 11 and 13,.
So, (11) = 121, (13) = 169
289 : 361; (17) = 289, (19) = 361
Therefore, 121 : 169 is the missing term.
Thus, the correct answer is (c).
