Clarissa is having lunch at a sandwich shop. She can choose white bread or pumpernickel bread. Her options for fillings are turkey, tuna, ham, or egg salad. Her choices for condiments are mayonnaise, salad dressing, or mustard. How many different sandwich choices does Clarissa have?

A. 36
B. 6
C. 24
D. 12.

Clarissa can make 2 choices for the bread (white or pumpernickel), 4 choices for the filling, and 3 choices for the condiment. Therefore, she has:

2 choices for bread * 4 choices for filling * 3 choices for condiment = 24 different sandwich choices

Therefore, the answer is C. 24.

To calculate how many different sandwich choices Clarissa has, we multiply the number of choices for each component together.

First, we have two options for bread: white bread or pumpernickel bread.

Then, we have four choices for fillings: turkey, tuna, ham, or egg salad.

Finally, we have three condiment options: mayonnaise, salad dressing, or mustard.

To find the total number of sandwich choices, we multiply the number of options for bread, fillings, and condiments together:

2 (bread options) * 4 (filling options) * 3 (condiment options) = 24

Therefore, Clarissa has 24 different sandwich choices.

The correct answer is C. 24.
