The multiple `5 xx 0.2` after rounding off will be

Options

A. `1`
B. `1.0`
C. `1.00`
D. `1.000`

Answer

To solve the question "The multiple 5 x 0.2 after rounding off will be", we will follow these steps:

### Step 1: Perform the multiplication
First, we need to multiply the two numbers:
\[ 5 \times 0.2 \]

### Step 2: Calculate the result
Calculating the multiplication:
\[ 5 \times 0.2 = 1.0 \]

### Step 3: Determine significant figures
Next, we need to consider the significant figures in our numbers:
- The number **5** has **1 significant figure**.
- The number **0.2** also has **1 significant figure** (the leading zero is not significant).

### Step 4: Apply the rule for significant figures
When multiplying numbers, the result should have the same number of significant figures as the factor with the least number of significant figures. Here, both factors have **1 significant figure**, so our final result should also be expressed with **1 significant figure**.

### Step 5: Round the result
The result we calculated is **1.0**. However, to express this in **1 significant figure**, we round it to:
\[ 1 \]

### Conclusion
Thus, the final answer after rounding off is:
\[ \text{Answer: } 1 \]

### Options
Looking at the options provided:
- Option A: 1
- Option B: 1.0
- Option C: 1.00
- Option D: 1.000

The correct answer is **Option A: 1**.
