Correct Answer

B. 4

Step 1

Concept

1, 2 and 3 are fixed, while 4 and 5 are optional. Hence \(2^2=4\) subsets.

Step 2

Why this answer is correct

The correct answer is B. 4. 1, 2 and 3 are fixed, while 4 and 5 are optional. Hence \(2^2=4\) subsets.

Step 3

Exam Tip

1, 2 और 3 निश्चित हैं, जबकि 4 और 5 वैकल्पिक हैं। इसलिए \(2^2=4\) उपसमुच्चय होंगे।
