The fixed factory overhead volume variance is

A) $2,000 favorable
B) $2,000 unfavorable
C) $2,500 unfavorable
D) $0

The fixed factory overhead volume variance measures the difference between the budgeted (standard) fixed overhead cost and the actual fixed overhead cost for the production volume achieved. It is calculated as follows:

Fixed factory overhead volume variance = (Budgeted fixed overhead cost - Actual fixed overhead cost)

In this case, the budgeted fixed overhead cost is based on a standard rate of $0.80 per hour for 10,000 hours, which is $8,000. The actual fixed overhead cost is given as $8,000. Therefore, the calculation is:

Fixed factory overhead volume variance = ($8,000 - $8,000) = $0

Since the result is $0, there is no volume variance for fixed factory overhead. Option (D) is incorrect.

Option (A) suggests that there is a favorable variance, meaning that the actual fixed overhead cost is lower than the budgeted amount. However, the calculation shows that the actual cost is equal to the budgeted amount, so there is no favorable or unfavorable variance.

Option (C) suggests that there is an unfavorable variance, meaning that the actual fixed overhead cost is higher than the budgeted amount. However, as mentioned earlier, the actual cost is equal to the budgeted amount, so there is no unfavorable variance.

Therefore, the correct answer is (B) - there is no fixed factory overhead volume variance.
