Pertama, ingat bahwa 

begin mathsize 14px style straight A cross times straight A to the power of negative 1 end exponent equals straight I end style 

Misalkan

begin mathsize 14px style straight A to the power of negative 1 end exponent equals open parentheses table row straight a straight b row straight c straight d end table close parentheses end style 

Maka,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell open parentheses table row cell negative 1 end cell 2 row 1 0 end table close parentheses cross times open parentheses table row straight a straight b row straight c straight d end table close parentheses end cell equals cell open parentheses table row 1 0 row 0 1 end table close parentheses end cell row cell open parentheses table row cell negative straight a plus 2 straight c end cell cell negative straight b plus 2 straight d end cell row straight a straight b end table close parentheses end cell equals cell open parentheses table row 1 0 row 0 1 end table close parentheses end cell row blank blank blank end table end style 

Sehingga kita peroleh

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row straight a equals 0 row straight b equals 1 row blank blank blank row cell negative straight a plus 2 straight c end cell equals 1 row cell 0 plus 2 straight c end cell equals 1 row straight c equals cell 1 half end cell row blank blank blank row cell negative straight b plus 2 straight d end cell equals 0 row cell negative 1 plus 2 straight d end cell equals 0 row cell 2 straight d end cell equals 1 row straight d equals cell 1 half end cell end table end style 

Sehingga didapat

begin mathsize 14px style straight A to the power of negative 1 end exponent equals open parentheses table row 0 1 row cell 1 half end cell cell 1 half end cell end table close parentheses end style 

Jadi, jawabannya adalah E.
