Explanation
Solution
1. Step 1: (B) Plotting
First, transfer the outputs from the truth table or Boolean expression into the K-map cells.
2. Step 2: (D) Grouping
Create the largest possible groups of 2n (1,2,4,8…) adjacent cells containing 1's (for SOP) or 0's (for POS).
3. Step 3: (C) Identification
Analyze the groups to find Prime Implicants and determine which are Essential (groups containing at least one cell that cannot be covered by any other group).
4. Step 4: (A) Writing the Expression
Convert the essential groups into their corresponding algebraic terms to form the final minimized expression.
Correct Order: B → D → C → A
Final Answer:
The correct option is (d) B, D, C, A.
