Bot The correct answer is D. 2,260.
This is a combination problem since we are choosing a group of toppings from a larger set without regard to order. The formula for combinations is:
nCr = n! / (r! * (n-r)!)
where n is the total number of items, and r is the number of items being chosen.
Plugging in our numbers, we get:
20C3 = 20! / (3! * (20-3)!)
= 20! / (3! * 17!)
= (20 * 19 * 18) / (3 * 2 * 1)
= 1,140
Therefore, the answer is option D. 2,260 is not the correct answer.
