D. 1.6

Answer

To round off the number 0.1576 to one digit after the decimal, we follow these steps:

### Step-by-Step Solution:

1. **Identify the digit to retain**:
- We want to round off to one digit after the decimal point. The first digit after the decimal in 0.1576 is 1 (the tenths place).

2. **Look at the next digit**:
- The digit immediately following 1 is 5 (the hundredths place). This digit will determine how we round the 1.

3. **Apply the rounding rule**:
- According to the rounding rules:
- If the next digit (5) is less than 5, we keep the digit we are rounding (1) as it is.
- If the next digit is greater than 5, we increase the digit we are rounding by 1.
- If the next digit is exactly 5, we check the digit we are rounding. If it is even, we leave it unchanged; if it is odd, we increase it by 1.
- In this case, the next digit is 5, and the digit we are rounding (1) is odd.

4. **Round the digit**:
- Since 1 is odd and the next digit is 5, we increase 1 by 1, resulting in 2.

5. **Final result**:
- Therefore, rounding 0.1576 to one digit after the decimal gives us 0.2.

### Final Answer:
0.2
