let setX: Set = [10, 20, 30, 40]
let setY: Set = [30, 40, 50, 60]
let intersectionSet = setX.intersection(setY)
print(intersectionSet.sorted())

A[10, 20]

B[30, 40]

C[50, 60]

D[10, 20, 30, 40, 50, 60]

Step-by-Step Solution

Solution:

Step 1: Understand intersection operation
Intersection returns elements common to both sets.
Step 2: Find common elements and sort
Common elements are 30 and 40. Sorting gives [30, 40].
Final Answer:
[30, 40] -> Option B
Quick Check:
Set intersection + sorted = [30, 40] [OK]

Quick Trick: intersection() finds common elements in Sets [OK]
