Option 2 describes a rotation issue, while options 2 and 3 describe tilt problems. These positioning errors can result in the manubrium and fifth thoracic vertebra being at the same level in the AP-PA chest projection. Option 4 does not affect the positioning of the manubrium and the fifth thoracic vertebra.
