The correct answer is "All contain a cell wall."

Explanation:

1. Not all bacteria are motile. Some bacteria have structures like flagella or pili that allow them to move, but others do not.

2. Not all bacteria cause disease. In fact, many bacteria are beneficial and play important roles in things like digestion and nutrient cycling.

3. All bacteria do contain a cell wall. This is a key characteristic of bacterial cells. The cell wall provides structure and protection.

4. All bacteria lack a nucleus. This is another key characteristic of bacterial cells. Instead of a nucleus, their genetic material is contained in a single circular chromosome. However, the question is about what is true for all bacterial cells, and the presence of a cell wall is a universal feature of all bacteria.
