The materials quantity variance is  2,000 unfavorable.
Material quantity variance
Standard quantity for actual output x standard price/pound = 5000 units x 2 pounds x $4 = $40000
Actual quantity for actual output x standard price/pound = 10500 pounds  x 4 = $42000
Thus, variance = 40000 - 42000 = $2000 unfavourable
Thus, the answer is (D)
