BIt allows variables to be changed anywhere
CIt requires more memory for variables
DIt makes code easier to debug and reason about
Step-by-Step Solution
Solution:

  1. Step 1: Identify the effect of immutability on debugging

    Immutable variables cannot change after assignment, so their values remain predictable.

  2. Step 2: Understand how predictability helps debugging

    When variables don't change unexpectedly, it is easier to find and fix bugs in the code.

  3. Final Answer:

    It makes code easier to debug and reason about -> Option D

  4. Quick Check:

    Immutability = Easier debugging [OK]
Quick Trick: Immutable variables keep values stable for easier debugging [OK]
Common Mistakes:
MISTAKES
  • Assuming immutability prevents all assignments
  • Thinking immutability wastes memory
