Avar value = 10;

Bint value = 10;

Cconst int value = 10;

Dmutable int value = 10;

Step-by-Step Solution

Solution:

Step 1: Understand immutability declaration
In low-level languages, the keyword const is used to declare variables that cannot be changed after initialization.
Step 2: Analyze options
int value = 10; and var value = 10; declare mutable variables. mutable explicitly allows modification. Only const int value = 10; enforces immutability.
Final Answer:
const int value = 10; -> Option C
Quick Check:
