Answer: Option D

Explanation:

To guarantee that one of each type of soda (orange, cream, and cherry) has been chosen, you need to remove enough sodas to ensure that you have at least 1 of each type.

First, remove 10 orange sodas. Now you have 10 orange, 15 cream, and 7 cherry sodas remaining.

Next, remove 15 cream sodas. Now you have 10 orange and 7 cherry sodas remaining.

Finally, remove 1 cherry soda.

At this point, you will have removed a total of 10 (orange) + 15 (cream) + 1 (cherry) = 26 sodas to guarantee that you have at least one of each type.
