Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.

8 : 63 :: 11 : ? :: 13 : 168

Given: 8 : 63 :: 11 : ? :: 13 : 168

63 = (8)² - 1 = 63

168 = (13)² - 1 = 168

Similarly,

? = (11)² - 1

? = 121 - 1

Thus, the correct option is (c)
