D. LXXXXIII

Answer

To find the sum of Raghu and Kavita's ages, we will follow these steps:

### Step 1: Identify the ages
- Raghu's age = 21 years
- Kavita's age = 72 years

### Step 2: Add their ages
- We will add Raghu's age and Kavita's age together:
\[ 21 + 72 \]

### Step 3: Perform the addition
- Breaking it down:
- Add the tens: \(20 + 70 = 90\)
- Add the units: \(1 + 2 = 3\)
- Now, combine the results:
\[ 90 + 3 = 93 \]

### Step 4: Write the final answer
- The sum of their ages is 93 years.

### Step 5: Convert the sum to Roman numerals
- To express 93 in Roman numerals:
- 90 is represented as XC (100 - 10)
- 3 is represented as III
- Therefore, 93 in Roman numerals is:
\[ XCIII \]

### Final Answer
The sum of Raghu and Kavita's ages is **93 years**, which is expressed in Roman numerals as **XCIII**.
