Answer:
2nd option is correct.
Explanation:
Variable over head    =   (Actual  Qty.  - Standard Qty. ) * Standard cost
Efficiency variance
                   = (10125-9000) * 30
                   =  $ 33750 (Un-Favorable)
2nd option is correct.
Variance is unfavorable because actual quantity used to produce is more than budgeted quantity allowed at that level of production.
