Assertion : In an OR gate if any of the input is high, the output is high.
Reason: OR gate is the most basic gate, with one input and one output

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true not but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that in an OR gate, if any one of the inputs is high (logic 1), the output will also be high (logic 1). This is a fundamental property of the OR gate.

2. **Understanding the Reason:**
- The reason provided claims that the OR gate is the most basic gate with one input and one output. However, this is incorrect because an OR gate typically has two inputs (though there are single-input OR gates, they are less common).

3. **Analyzing the Truth Table of an OR Gate:**
- Let's construct the truth table for a two-input OR gate:
```
A | B | Output (A + B)
----------------------
0 | 0 | 0
0 | 1 | 1
1 | 0 | 1
1 | 1 | 1
```
- From the truth table, we can see that if either A or B is high (1), the output is high (1).

4. **Conclusion:**
- The assertion is true because the output is high if any input is high.
- The reason is false because the OR gate is not limited to one input; it typically has two inputs.

5. **Final Evaluation:**
- Since the assertion is true and the reason is false, the correct conclusion is that the assertion is correct, but the reason is incorrect.

**Answer: The assertion is true, but the reason is false.**
