Question

what is the number - one cause of spoiled meat? a moisture b smoke c heat d dirt

Explanation:

Moisture provides an ideal environment for bacteria growth. Bacteria are the main agents that cause meat spoilage. Smoke is often used for preservation (like in smoked meats), heat can be used for cooking (which can prevent spoilage if done properly, but excessive heat might not be the number - one cause in general spoilage scenarios in a non - cooking context), and dirt is more of a contaminant but not as fundamental as moisture in creating the right conditions for spoilage.

Answer:

A. moisture
