Rationale: Simple squamous epithelial tissue is the correct answer because it consists of a single layer of flat cells, which is characteristic of the tissue shown in Figure 1. This type of tissue is found in areas where rapid diffusion or filtration is required, such as the lining of blood vessels and the alveoli of the lungs. Its thin structure allows for efficient exchange of gases and nutrients.

Correct Answer: B

Rationale: Lower motor neuron is the correct answer because damage to these neurons directly affects the muscles they innervate, leading to atrophy, weakness, and loss of reflexes. This occurs due to the disruption of the neural connection between the spinal cord and the muscle, resulting in denervation and subsequent muscle wasting.
