B
Nervous tissue
C
Muscle tissue
D
Connective tissue
Verified step by step guidance1
Examine the figure provided in the problem. Identify the key structural features of the cells, such as their arrangement, shape, and the amount of extracellular matrix present.
Recall the defining characteristics of epithelial tissue: tightly packed cells with minimal extracellular matrix, forming continuous sheets that cover surfaces or line cavities.
Compare the observed features in the figure to the characteristics of the four tissue types: epithelial tissue, nervous tissue, muscle tissue, and connective tissue. For example, connective tissue typically has abundant extracellular matrix, which is not observed here.
Eliminate options that do not match the observed features. For instance, nervous tissue is specialized for signal transmission and does not typically exhibit tightly packed cells with minimal extracellular matrix.
Conclude that the tissue type most consistent with the observed arrangement of tightly packed cells and minimal extracellular matrix is epithelial tissue.
