C. fewer and fewer; smaller and smaller    D. smaller and smaller; fewer and fewer

Answer

D

【解析】

句意：大熊猫的数量正在变得越来越小，因为野生动植物的生存区域越来越少了。the number of……表示“……的数量”，表示数目大小只能用large，small来修饰，smaller and smaller越来越小，排除A,C选项；less是little的比较级，修饰不可数名词，fewer是few的比较级，修饰可数名词，areas 是可数名词的复数形式，只能用fewer and fewer来修饰。故答案为D。
