A. which
B. whose
C. with its
(答案→)D. with whose
解析：考查从句，with one’s help固定句型，意思“在……帮助下”，由后面的句子should be made full use of to promote the social development，可以知道前面的句子help we human beings have stepped into the information age是个从句，句子意思“在电脑的帮助下，我们人类进入了信息时代，充分利用电脑提高社会发展”，固定词组 make full use of意思“充分利用”， step into意思“干预”，所以选D
