Solution

The correct option is D

O- and AB+


The correct option is D.

Explanation of the correct option:

  1. The ability of a substance or equipment to operate in contact with blood without causing unfavourable reactions is known as blood compatibility.
  2. Because the O- lacks both antigens for the blood group and antigens for the Rh factor, it is a universal donor.
  3. Because it has no antibodies to A, B, and Rh, the AB- is a universal acceptor and may absorb red blood cells from any kind of donor.

Explanation of the incorrect option:

Option A:

O+ can donate blood only to O+, A+, B+ and AB+

Option B:

AB- can receive blood only from AB-, A-, B- and O-

Option C:

O+ can donate blood only to O+,A+, B+ and AB+.

Final answer: Universal donor and universal acceptor is O- and AB+.
