The logic gate is an electric circuit which

Options

A. makes logic decisions
B. allows electrons flow only in one
C. works binary algebra
D. alternates between 0 and 1 values

Answer

### Step-by-Step Solution

1. **Understanding Logic Gates**: A logic gate is an electronic circuit that processes binary inputs to produce a binary output. Each logic gate can have one or more inputs, and the output is typically a single binary value.

2. **Binary Values**: The inputs to a logic gate can only take two values: 0 (representing a low state) and 1 (representing a high state). This binary nature is fundamental to how logic gates operate.

3. **Functionality of Logic Gates**: Logic gates perform basic logical functions that are fundamental to digital circuits. They can perform operations such as AND, OR, NOT, NAND, NOR, and XOR, which correspond to logical multiplication and addition.

4. **Logical Decisions**: The primary function of a logic gate is to make logical decisions based on the combination of its inputs. For example, an AND gate will output a 1 only if all its inputs are 1, while an OR gate will output a 1 if at least one of its inputs is 1.

5. **Conclusion**: Therefore, we can conclude that a logic gate is an electric circuit that makes logical decisions based on its input values.

### Final Answer
The logic gate is an electric circuit which makes logical decisions.
