What is wrong with this SwiftUI code?

struct ExampleView: View {
  @State var text: String
  var body: some View {
    Text(text)
  }
}

AThe @State variable must have an initial value

BText cannot display a String variable

CThe body property must be a function

DThe struct must inherit from UIViewController

@State variables must have an initial value because SwiftUI manages their storage.
Step 2: Verify other parts
Text can display String, body is a computed property, and struct inherits from View, not UIViewController.
Final Answer:
The @State variable must have an initial value -> Option A
Quick Check:
@State needs initial value = B [OK]

Quick Trick: Always initialize @State variables when declaring [OK]
