Is the Dismissive Avoidant Attachment Style an Exception to the "No

Is the dismissive avoidant attachment style an exception to the "no man is an island" general rule? That is, are dismissive types really "islands" that don't need or want affection and approval from others? A recent study by Carvallo and Gabriel suggests that the answer is

A) yes, dismissives are islands because they rejected feedback that others liked and accepted them.
B) yes, dismissives are islands because they showed no response to feedback that others liked and accepted them.
C) no, dismissives are not islands because they experienced more positive feelings in response to feedback that others liked and accepted them than did people with a low dismissive view.
D) no, dismissives are not islands because this category of attachment style cannot be reliably assessed or evaluated.
