The correct answer is: B. 5436.80
The number format ‘#,##0.00’ tells Excel to display the number with a leading space, commas to separate thousands, and two decimal places. In this case, the number 5,436.8 would be formatted as 5436.80.
Option A, 5430, is incorrect because it does not include the decimal point. Option C, 5436.8, is incorrect because it does not include the leading space. Option D, 6.8, is incorrect because it does not include the thousands separator.
