Answer:

The blood type that can donate to the recipient B- is O-. This is because the O- is known as the universal donor since it lacks both the A and B antigen on the red blood cells. Hence, it will not be recognized as foreign in the recipient's body that doesn't have antigens on their red blood cells either.

Blood donation is a voluntary process where blood donors give their blood to be used in transfusions and other medical procedures. Blood donation is an essential service that saves millions of lives each year.

There are four major blood types - A, B, AB, and O. Blood types are categorized by the presence or absence of certain antigens on red blood cells.

There are four types of blood donors:

1. Voluntary non-remunerated blood donors

2. Family/replacement blood donors

3. Paid blood donors

4. Donors of autologous blood
