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:

$\{[77,68,86,73],[96,87,89,81],[70,90,86,81]]$

Which of the following statements a$)$ b$)$ or ci is false?

The following nested for statement outputs the rows of the two$-$dimensional list a one row at a time:Writing the list as follows makes its row and column tabular structure clearer:The element names in the last column all have $3$ as the second index.All of the above statements are true.
