Urinary bladder is lined by stratified epithelium/transitional epithelium.

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the type of epithelium that lines the urinary bladder. We need to identify the correct type of epithelial tissue.

2. **Defining Stratified Epithelium**: Stratified epithelium consists of two or more layers of cells. Its primary function is to provide protection. It can be composed of different cell shapes, such as squamous, cuboidal, or columnar.

3. **Defining Transitional Epithelium**: Transitional epithelium is a specialized type of stratified epithelium. It is primarily composed of cuboidal cells. The unique feature of transitional epithelium is its ability to stretch and contract depending on the volume of the bladder. This property allows it to accommodate varying amounts of urine.
