The correct method to call to specify a Runnable that should execute in the GUI thread is runOnUiThread. This method is specific to the Activity class and ensures that the Runnable is executed on the main UI thread. This is important because UI elements can only be updated from the main thread. Option B (executeOnUIThread) is not a valid method for the Activity class and options C and D are incorrect.
