**Hint**: The given problem revolves around the concepts of basic arithmetic and roman numbers. In the given question, we are required to evaluate the difference of two numbers given to us in the problem itself. The numbers provided to us are $ 1000 $ and $ 400 $ . So, we have to compute the difference of these two numbers and then represent the difference in the form of roman numerals. We break down the information given to us to try and identify what must be done in order to solve the problem.

**:**

__Complete step-by-step answer__So, we have to compute the difference of the two numbers: $ 1000 $ and $ 400 $ . So, we get the difference as,

$ \Rightarrow 1000 - 400 $

Simply subtracting $ 400 $ from $ 1000 $ , we get,

$ \Rightarrow 600 $

Hence, we get the difference of the two numbers $ 1000 $ and $ 400 $ as $ 600 $ .

Now, we have to represent the difference in the form of roman numerals.

We know that the roman numeral for representing $ 100 $ is C and roman numeral for representing $ 500 $ is D. Also, we know that the roman numerals are added when written on the right side of other base roman numerals.

So, we get the roman numeral for the difference of $ 1000 $ and $ 400 $ as,

$ \Rightarrow 600 = DC $

Hence, option (D) is correct.

**So, the correct answer is “Option D”.**

**Note**: When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combinations of mathematical symbols is called a mathematical expression. Roman numbers are just another system of numerical notation. One must remember the roman number notations so as to solve such questions.
