Show answer and explanation
Correct Answer
C. 128 / 128
ExplanationStep 1: A set with n elements has 2^n subsets. Step 2: For n = 7 we get 2^7 = 128. Step 3: Remember power of 2 for subset count.
Step 1: n elements वाले set के subsets 2^n होते हैं। Step 2: n = 7 रखने पर 2^7 = 128। Step 3: Subset count में 2 की power याद रखें।
