The correct Answer is:
To solve the problem, we need to analyze the given sets and determine their relationships. Let's go through the steps systematically. ### Step-by-Step Solution: 1. **Identify the Sets**: - Set A = {w, o, l, f} - Set B = {f, l, o, w} - Set C = {f, o, w, l} - Set D = {f, o, l, l, o, w} 2. **Remove Duplicates in Set D**: - Set D has duplicates (l and o appear twice). In set theory, we only consider distinct elements. - Therefore, Set D can be simplified to: - Set D = {f, o, l, w} 3. **Rearranging Elements**: - In set theory, the order of elements does not matter. We can rearrange the elements in any order. - Thus, we can write: - Set A = {w, o, l, f} = {f, o, l, w} (rearranged) - Set B = {f, l, o, w} = {f, o, l, w} (rearranged) - Set C = {f, o, w, l} = {f, o, l, w} (rearranged) - Set D = {f, o, l, w} (after removing duplicates) 4. **Compare the Sets**: - Now we can see that: - Set A = {f, o, l, w} - Set B = {f, o, l, w} - Set C = {f, o, l, w} - Set D = {f, o, l, w} - Therefore, all sets A, B, C, and D are equal. 5. **Conclusion**: - Since all sets are equal, we conclude that: - A = B = C = D ### Final Answer: The correct option is **Option 4: A = B = C = D**. ---
