B. `1.4`
C. `1.0`
D. `1`

Answer

To find the value of \( \sqrt{2.0} \) and express it with one significant figure after the decimal, we can follow these steps:

### Step 1: Calculate \( \sqrt{2.0} \)
The square root of 2 is approximately 1.41421356.

### Step 2: Round to One Significant Figure After the Decimal
Since we need to report the answer with one significant figure after the decimal point, we look at the first digit after the decimal, which is 4.

- The digit following 4 is 1, which is less than 5. Therefore, we round down.

Thus, we round 1.41421356 to 1.4.

### Step 3: Final Answer
The final answer for \( \sqrt{2.0} \) rounded to one significant figure after the decimal is **1.4**.
