Based on the given description above, the correct answer would be option D. 63. How is that so.
So here it is: 1 combination of 3 pasta meals (1*3)
                     1 combination of 7 chicken value meals (1*7)
                     1 combination of 3 fish meals (1*3)
(1*3)(1*7)(1*3) would be 63.
That makes Ping can choose a dinner meal in 63 ways.
Hope that this is the answer you are looking for.
