According to Hazan and Shaver (1987) A. romantic relationships in adulthood follow the same form as attachment relationships in infancy. B. those who had ambivalent attachments in infancy are doomed never to fall in love as adults. C. those who had avoidant attachments in infancy often overcompensate by becoming excessively intimate in their adult love relationships. D. all of the above are the case.

Start by carefully reading each of the four options provided: A. romantic relationships in adulthood follow the same form as attachment relationships in infancy. B. those who had ambivalent attachments in infancy are doomed never to fall in love as adults. C. those who had avoidant attachments in infancy often overcompensate by becoming excessively intimate in their adult love relationships. D. all of the above are the case.

Remember that Hazan and Shaver focused on the importance of attachment styles in infancy and how those styles carry over to the way people experience romantic relationships in adulthood. They identified three primary attachment styles: secure, avoidant, and anxious/ambivalent.

Examine each option and determine whether it is consistent with Hazan and Shaver's theory: A. This option suggests a link between attachment styles in infancy and adult romantic relationships, which is consistent with Hazan and Shaver's theory. B. This option implies that people with ambivalent attachments in infancy will never experience romantic love, which is an extreme statement and not fully consistent with the theory. C. This option suggests that people with avoidant attachments may overcompensate with excess intimacy in adulthood, but it does not necessarily align with the theory's core focus on the connection between attachment styles in infancy and adult romantic relationships. D. This option claims that all three of the above statements are true, but since options B and C are not entirely consistent with Hazan and Shaver's theory, this option cannot be correct.

Based on the analysis in Step 3, the correct answer is: A. romantic relationships in adulthood follow the same form as attachment relationships in infancy.
