Answer:
"B"
Step-by-step explanation:
Variance analysis is a performance tool used in evaluating the differences in the budgeted , standard and actual performance purposely to know how well a production process is fairing and any room for improvement.
If the standard direct labor rate is $12, then the standard labor cost is $4000*12 = $4,800.
In the situation where the actual direct labor cost is $47,040 , that means that a value of $960 has been saved on the direct labor cost which is a favorable variance.
