Answer: Option B
:
B
For theset of Roman numerals X, XI the values are:
X = 10
XI = 11
10 < 11.
So, they are not arranged in descending order.
For theset of Roman numeralsXLV, XXII, LI, XI:
XLV = 45 and LI = 51.
45 < 51.
Therefore the set of Roman numeralsXLV, XXII, LI, XI are not arranged in descending order.
For theset of Roman numeralsXXXVIII, XLIX, LII, LXIV:
LII = 52 and LXIV = 64.
52 < 64
Therefore the set of Roman numeralsXXXVIII, XLIX, LII, LXIV are not in descending order.
For theset of Roman numerals LXI, XLIV, XXXVIII, XXV the values are:
LXI = 50 + 10 + 1 = 61
XLIV = 40 + 4 = 44
XXXVIII = 10 + 10 + 10 + 5 + 3 =38
XXV = 10 + 10 + 5 = 25
Since, 61, 44, 38, 25 are in descending order soLXI, XLIV, XXXVIII, XXV are arranged in descending order.
