Stale callback in a long effect

One second after Splash appears, the parent passes a new onTimeout lambda. Which lambda is called after 3 seconds?

@Composable
fun Splash(onTimeout: () -> Unit) {
  LaunchedEffect(Unit) {
    delay(3000)
    onTimeout()
  }
}

A.The newest lambda, because composables always read the latest parametersB.The original lambda captured when the effect started; use val currentOnTimeout by rememberUpdatedState(onTimeout) and call that insteadC.Both lambdas, one after the otherD.Neither; a new lambda parameter restarts every LaunchedEffect in the composable, so the 3 second timer resets each time the parent passes one
