Verified by Toppr

The RBC's of frog are nucleated while human RBC's are enucleated.
The absence of nucleas allows the red RBC's to contain more haemoglobin and, therefore, carry more oxygen molecules. It also allows it to have its distinctive bi-concave shape which aids diffusion.
So, the correct option is 'Nucleated RBCs'.
