Suggested Answer: D 🗳️
Syntax: protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) onMeasure() measures the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.
