Verified step by step guidance

Step 1: Begin by understanding the primary functions of epithelial tissue. Epithelial tissue is one of the four main types of tissues in the body, and its primary roles include protection, absorption, secretion, and filtration.

Step 2: Analyze the options provided in the question. The first option, 'Protection of underlying structures,' aligns with one of the primary functions of epithelial tissue, as it forms protective barriers on surfaces such as skin and organ linings.

Step 3: Evaluate the second option, 'Contraction to produce movement.' This function is associated with muscle tissue, not epithelial tissue, as muscle tissue is specialized for contraction and movement.

Step 4: Consider the third option, 'Transmission of electrical impulses.' This function is characteristic of nervous tissue, which is specialized for communication and signal transmission, not epithelial tissue.

Step 5: Examine the fourth option, 'Storage of minerals.' This function is primarily associated with bone tissue, which is a type of connective tissue, and not epithelial tissue. Therefore, the correct answer is 'Protection of underlying structures,' as it matches the primary function of epithelial tissue.
