Final answer:
None of the food items listed (sugar, salt, flour, yeast) are directly used in the production of dynamite; dynamite is made with nitroglycerin, which is stabilized by diatomaceous earth.
Step-by-step explanation:
The food item used in the production of dynamite is not a typical kitchen ingredient but is connected to the idea that some food items can exhibit energy-releasing properties. Flour is one example, as it is highly flammable and can cause explosions under the right conditions, but it is not used in dynamite.
Instead, dynamite contains nitroglycerin, which is stabilized by diatomaceous earth. Sugar, another common food item, while sharing some similar explosive characteristics under certain conditions, does not play a role in the making of dynamite.
The energy in carbohydrates like sugar and flour is an example of chemical potential energy, which is different from the explosive potential seen in dynamite compositions.
Therefore answer is C) Flour.
