<span>The most basic universal indicators of human development are life expectancy, literacy, and standard of living. Only health would not be considered as part of these indicators, because it doesn't say anything about human development. Life expectancy refers to the length of someone's life. Literacy is the state of being literate, meaning knowing how to read and write. Standard of living is self-explanatory - whether you live good and have money or the opposite.</span>
Answer:
The correct answer would be "T-lymphocytes would bind self-antigens".
Negative selection of T-lymphocytes takes place in the cortico-medullary junction in the thymus.
It removes T-lymphocytes which show high-affinity binding with self-antigen. Thus, it helps in introducing self-tolerance in T-lymphocytes.
In absence of negative selection, T-lymphocytes which show high-affinity binding for self-antigen would survive and develop into mature T-lymphocytes.
Consequently, T-lymphocytes would able to bind to self-antigens of the body which can result in autoimmune disease.
