Why is marginal (direct) costing better suited for a break-even analysis than absorption costing?

a) Because the non-linear sales revenues or cost lines do not provide a problem for marginal costing.

b) Because the production of different products with different contribution margins, provide no problem for marginal costing.

c) Because the cost functions in marginal costing do not need to be known.

d) Because the difference between production and sales do not prose a problem for marginal costing.
