Step-by-step explanation:

okay relax dw it's all good

1. B : just count one whole pizza and the addition three out of 8

2. B addition question : 2+13+1+4+2 break it up

2+13=15+1=16+4=20+2=22

3. multiply 9 and 5. do the grouping thing if you need help

4. possible combinations can be done by drawing a big tree graph. I have attached an example above in image. count along each branch. there are 8 combinations.

5. this is called a 90° angle

based on context clues you gave i'm assuming the answer would be c.
