Question
**Question 37**

**Which choice is an opposite of the following code**
```
(10 <= X) && (X <= 100)
```

**Options:**
1. (10 <= X) || (X >= 100)
2. (10 > X) && (X < 100)
3. (10 = X) && (X = 100)
4. (10 > X) || (X > 100)

To understand the question correctly, let's break down what the given code does:
- The expression `(10 <= X) && (X <= 100)` is a logical condition that checks if the variable `X` is between 10 and 100 (inclusive).

Now, we need to find the logical opposite, or negation, of this expression.

Explanation of each given option:

1. **(10 <= X) || (X >= 100)**: This would check if `X` is greater than or equal to 10 OR if `X` is greater than or equal to 100. This is not the opposite.
2. **(10 > X) && (X < 100)**: This would check if `X` is less than 10 AND if `X` is less than 100. This is incorrect.
3. **(10 = X) && (X = 100)**: This would check if `X` is exactly 10 AND exactly 100, which is not possible and hence incorrect.
4. **(10 > X) || (X > 100)**: This option checks if `X` is less than 10 OR if `X` is greater than 100. This is the correct opposite of the given condition.

Therefore, the right answer is:
```
(10 > X) || (X > 100)
```
