The correct answer option is {A}
Explanation
When determining the number of decimal places we count the number of digits which comes after the decimal. In our question,234.567 has 3 decimal places. To write it in 1 decimal place, we count ones from the decimal place to arrive at digit 6 which will round off the tenth digit 5 to get 234.6(simple math)
