Identify the error in this model-view separation code:

class Model { int health = 100; void damage(int d) { health -= d; } } class View { void show() { print("Health: " + health); } }

ANo error, code is correct.

BModel class should not have damage method.

CView class should update health value.

Step-by-Step Solution

Solution:

Step 1: Check access between classes
The View class tries to print 'health' but does not have access to Model's health variable.
Step 2: Understand separation rules
View should get health value from Model via method or parameter, not direct access.
Final Answer:
View class cannot access 'health' directly from Model. -> Option D
Quick Check:
View needs data from Model, no direct access [OK]

Quick Trick: View must get data from Model, not access variables directly [OK]
