I think it is B if I’m Wrong I’m sorry
<span>Most X-linked conditions are recessive. This means that in a person with two X chromosomes (most females), both copies of a gene (i.e., one on each X chromosome) must have a change or mutation whereas in a person with one X chromosome (most males), only one copy of a gene must have a mutation. A female with a mutation in one copy of a gene on the X chromosome is said to be a “carrier” for an X-linked condition</span>
I think that this is true, but also that this is true not only for psychologists, but for people in general - we should be taking the most ethical decision in any circumstance. However, this might be problematic, as people disagree about what is ethical - still, considering ethics in decision-taking is a good way of maximizing people's benefit and making sure we are not hurting anyone
So the statement is true.
I would say that however, psychologists have even more responsibility to make ethical decisions because they are specifically trained to do so.
