#### Circuits:
**A)**
- **Diagram:** This circuit is composed of a single OR gate with two inputs.
- **Algebraic Expression:** \( A + B \)
- **Truth Table:**
| A | B | Output |
|---|---|--------|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
---
**B)**
- **Diagram:** An OR gate with one input connected to ground and the other input variable.
- **Algebraic Expression:** \( A + 0 \) (or simply \( A \))
- **Truth Table:**
| A | Output |
|---|--------|
| 0 | 0 |
| 1 | 1 |
---
**C)**
- **Diagram:** An OR gate with one input connected to a ground symbol.
- **Algebraic Expression:** \( 0 \)
- **Truth Table:**
| Output |
|--------|
| 0 |
---
**D)**
- **Diagram:** An OR gate with inputs grounded, meaning both inputs permanently receive zero.
- **Algebraic Expression:** \( 0 + 0 \) (equals 0)
- **Truth Table:**
| Output |
|--------|
| 0 |
