The correct option is B CCXXX
The first Roman numeral is CCLXI
CCLXI = 100 + 100 + 50 + 10 + 1 = 261
The second Roman numeral is DCCCIX
DCCCIX = 500 + 100 + 100 + 100 + 9 = 809
The third Roman numeral is LXIV
LXIV = 50 + 10 + 4 = 64
The fourth Roman numeral is CMIV
CMIV = 900 + 4 = 904
So, the we need to find 261 + 809 + 64 - 904
261 + 809 + 64 - 904 = 1134 - 904 = 230
