Correct option is C)

  • The frog heart is divided into 3 chambers two atria and a single ventricle. 
  • The atrium receives deoxygenated blood from the blood vessels (veins) that drain the various organs of the body. 
  • The left atrium receives oxygenated blood from the lungs and skin (which also serves as a gas exchange organ in most amphibians).
  • Both atria open into a single ventricle due to which there is mixing of Oxygenated and deoxygenated blood. 
Therefore, the correct answer is option C.
