Correct answer: C
Answer: 36
Reason: We need to choose 2 different toppings from 9 available toppings. The order in which the toppings are chosen does not matter, and we do not allow repetition.
Use combinations (n choose 2):
Formula: C(n,2) = n(n−1)/2
Apply with n = 9: C(9,2) = 9 × 8 / 2 = 36
Therefore, the shop keeper can make 36 different pizzas with 2 different toppings.
