Bonnie is 3 months old and her parents attend only inconsistently to her needs. Sometimes, they are very attentive, feeding her promptly when she cries and comforting her when she seems upset. Other times, Bonnie cries for a long time before her parents attend to her.

a) feelings of isolation.
b) a sense of inferiority.
c) a sense of despair.
d) a general sense of mistrust.
