Final answer:
During the second trimester of pregnancy, the most typical psychosocial response is emotional stability and a sense of well-being as initial discomforts subside and the connection with the baby strengthens.
Step-by-step explanation:
The question pertains to normal psychosocial responses to pregnancy during the second trimester. During this stage, which occurs during weeks 13 to 28, a pregnant person may feel more energized and relief from nausea and vomiting that may have occurred during the first trimester. This time is often characterized by emotional stability and a sense of well-being, as initial discomforts subside and the physical presence of the baby becomes more tangible with fetal movement.
It is also a time when significant physiological changes continue to occur in the mother's body, including weight gain from the growing fetus, enlarged uterus, amniotic fluid, placenta, and increased blood volume. These changes, alongside hormonal adjustments, can augment appetite and cause other physical symptoms, but they do not generally lead to social withdrawal or decreased interest in the pregnancy.
Therefore, the most typical psychosocial response during the second trimester is option b. Emotional stability and a sense of well-being.
