Answer:
d. sum of the materials price variance and the materials quantity variance.
Step-by-step explanation:
Total variance: The total variance comprises of material price variance and the material quantity variance.

Total variance = Material price variance + material quantity variance
where,
Material price variance= Actual Quantity × (Standard Price - Actual Price)
And, the material quantity variance = Standard Price × (Standard Quantity - Actual Quantity)
