Choose the odd one out giving reason

Dear student,
Please find below the answer:

1. Plasma is the odd one out. Rest all are types of blood vessels.
2. Monocytes is the odd one out. Rest all are granular WBCs.
3. Rh+ is the odd one out. Rest all are types of blood groups.
4. Lymph is the odd one out. Rest all are types of blood cells.
5. Water cycle is the odd one out. Rest all are related to the cardiac cycle of heart.

Hope this clears your doubt.
Regards.
