Correct answer: B
Option B:
The primary purpose of using Don't Care Condition conditions in a Karnaugh Map (K-Map) is:
✅ To simplify the Boolean expression further by reducing the number of logic gates required.
Explanation:
Don’t Care conditions represent input combinations that never occur or whose outputs do not matter.
In K-Map simplification, they may be treated as either 0 or 1, whichever helps form larger groups.
Larger groups produce simpler Boolean expressions.
Benefits:
Reduces number of gates
Reduces circuit complexity
Reduces hardware cost
Improves speed
