A diagnostic test for tuberculosis (TB) involves injecting antigen (from the bacterium that causes TB) under the skin and then waiting a few days for a reaction to appear. This test is NOT useful for diagnosing TB in AIDS patients. Explain why

This test is called TB Skin Test.

Some people who are infected with both HIV and TB bacteria will not react to the TB skin test. This is because the immune system is not working properly. Anyone who is HIV infected and has a negative skin test should also have other medical tests, if they have symptoms of TB disease.

Answer is option "A"

Explanation:

The concept of actor-observer bias states that the causes of behaviors and events in our lives are motivated by attribution. Attribution is an inference that we make about our behaviors and the behaviors of others. The attributions we make depend directly on whether we are the actor or the observer. The actor-observer difference inclination will be progressively articulated in circumstances where the results are negative. For instance, in a circumstance where an individual encounters something negative, the individual will regularly accuse the circumstance or conditions. When something antagonistic happens to someone else, individuals will frequently censure the person for their own decisions, practices, and activities.Hence, the right answer is option A "actor-observer perspective".
