For dinner at a restaurant, there are x choices of appetizers, y + 1 main courses, and z+1 choices of dessert. How many total possible choices are there if you choose 1 appetizer, 1 main course, and 1 dessert for your meal?
Choose the correct choice from the following answers
A) x + y + z + 1
B) xyz + xz
C) xy + z + 1
D) xz+x+xyz+xy
E) xyz + 1/2
x appetizers,   y + 1 main courses,   z+1 dessert   Required: 1 appetizer, 1 main course, and 1 dessert   Number of ways possible = xC1*(y+1)C1*(z+1)C1 {NC1 = N! / (N-1)!*1! = N}   Hence, number of ways = x(y+1)(z+1) = (x + xy)(z+1)=xz+x+xyz+xy   Correct Option: xz+x+xyz+xy
<result>D</result>
