Answer:
a. high fixed costs in its production process
Step-by-step explanation:
Operating leverage is used to compare fixed cost and variable cost of producing a good.
High operations leverage occurs when fixed cost is high and variable cost is low.
This means the production process uses more of fixed assets.
Also high operations leverage are characterised by high product margin an low variable cost. So the higher the revenue the higher the operational income.
This implies that companies make high profit from each additional unit since variable cost is low.
