c. a biopsychosocial approach.
Explanation:
A psychosocial approach is a model of medicine and psychology that studies the cause and evolution of illness, addiction, and disorder considering biological, psychological, and social aspects. It is opposed to the biomedical model, which is centered on disease and restricted to biological factors.
From a biopsychosocial perspective, health and disease are understood as a result not only of the interaction of the biological factors of the individual's organism, but also of the environment in which they live and their social relationships. An example of this can be seen in the question above, where Mark's addiction is explained by the biological and social factors surrounding him.

Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.
