• A. down, inwards
  
• B. up, inwards
  
• C. down, outwards
  
• D. up, outwards
  

Answer 1

The correct option is C down, outwards

• Inhalation is the process of taking in oxygen rich air.
• During inhalation, the diaphragm moves down and gets flattened whereas the ribs move outward.
• This movement increases the volume of the chest cavity and air rushes into the lungs.
