The case of Genie and her failure to acquire meaningful language ability best supports D. the critical period theory.
Genie was a wild child - she lived in nature, surrounded by animals and didn't have any contact with humans or human language. This is why it was really difficult for her to acquire a language once she grew older - critical period is very important when learning a language because a language is acquired fastest when the child is young.

Like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
