Fifth intercostal space near the left midclavicular line
Third intercostal space at the left sternal border

B. The second intercostal space at the right sternal border: This area is typically used to auscultate the aortic valve.
C. Fifth intercostal space near the left midclavicular line: This area is used to auscultate the mitral valve, not Erb's point.
