Correct option is D
Given:
Roman numerals: CXIX, XCIX, CXXI, CIX, CXX
Arrange them in increasing order.
Formula Used:
Roman numeral values:
I = 1, V = 5, X = 10, L = 50, C = 100
Solution:
Convert each Roman numeral:
XCIX = 99
CIX = 109
CXIX = 119
CXX = 120
CXXI = 121
Increasing order (smallest to greatest):
99, 109, 119, 120, 121
So, Roman numerals in increasing order are:
XCIX, CIX, CXIX, CXX, CXXI
Thus, Option (D) matches.
