Accounting profit differs from economic profit because:

A) of differences in the manner in which revenue is calculated.
B) economic costs include explicit costs,while accounting costs do not.
C) accounting costs are generally higher than economic costs because accounting costs include explicit and implicit costs,while economic costs include only explicit costs.
D) economic costs are generally higher than accounting costs because economic costs include all opportunity costs,while accounting costs include explicit costs only.

Accounting profit is calculated by deducting explicit costs (direct expenses) from total revenue, while economic profit takes into consideration both explicit and implicit costs (opportunity costs). Economic profit provides a more accurate picture of a firm's profitability as it accounts for the value of the resources that could have been used elsewhere, while accounting profit only considers the expenses that have already been incurred. Therefore, the economic cost is generally higher than the accounting cost, making option D the correct answer.
