Ramona wants to buy pizza for her friends and family gathering. He stops by Nine Wonders Pizza and saw the four options. She should select humongous cheese pizza because large pizza won't be sufficient for the gathering. But if she buys 2 large pizzas, then the price she will have to pay will be slightly higher than buying one humongous cheese pizza. She would pay $24.99 for one 24 inch pizza, where as she can buy two 18 inch pizzas in $25.98. So she should go with option C.
