let names = ["Anna", "Bob", "Cindy", "David"]
for name in names where name.count == 4 {
    print(name)
}

APrints all names longer than 4 letters

BPrints all names regardless of length

CPrints all names shorter than 4 letters

The condition name.count == 4 filters names with exactly 4 letters.
Step 2: Check which names match
"Anna" (4), "Bob" (3), "Cindy" (5), "David" (5), so only "Anna" prints.
Final Answer:
Prints all names with exactly 4 letters -> Option D
Quick Check:
Filter by length == 4 = Prints matching names [OK]

Quick Trick: Count characters to filter strings with where [OK]
