It is not socially for parents to leave children unattended at that age.

A. accessible

B. adorable

C. adaptable

D. acceptable

答案：

A. accessible

B. adorable

C. adaptable

(答案→)D. acceptable

解析：

acceptable意为“可接受的,合意的”。根据所提供的情景“to leave children unattended at the age”可判断出社会不允许父母在孩子那种年龄时不进行照顾。accessible意为“易接近的,可到达的,易受影响的,可理解的”；adorable意为“可崇拜的,可爱的”；adaptable意为“能适应的,可修改的”。
