Answer to Question 1

B

Answer to Question 2

The rationale for df = (r-1) (k-1) is that this quantity represents the number of cell frequencies that are free to vary. Given that we know the sample size (the total number of observations in the table), we need only know the contents of (r-1) rows and (k-1) columns in order to completely fill in the cells within the r x k table.
