ExplanationThis problem is about combinations, because the order of the dishes does not matter.

Since you’re choosing 4 dishes, start by drawing 4 blanks. On top, write the number of choices: 12 choices for the first dish, then 11, 10, and 9. On the bottom, start with the size of the smaller group and count down: 4, 3, 2, and 1.

Cancel the numbers on the bottom, and the numbers on top will multiply to 495.

Hence option C is correct!
