Consider a two$-$dimensional list with three rows and four columns $($i$.$e$.,$ a $3-$by$-4$ list$)$ that might represent the grades of three students who each took four exams in a course:a $=1[77,68,86,73],[96,87,89,81],[70,90,86,81]1$Which of the following statements a$),$ b$)$ or c$)$ is false? Writing the list as follows makes its row and column tabular structure clearer:a $=[77,68,86,73],$ # first student's grades$96,87,89,811,$ # second student's grades $[70,90,86,81]$ # third student's grades The following nested for statement outputs the rows of the two$-$dimensional list a one row at a time:for row in a:for item in row:print$($item$,$ end$=\text{'})$print$)$ The element names in the last column all have $3$ as the second index. All of the above statements are
