Final answer:
The correct answer is D. a $75,000 increase because the provision for bad debt is a non-cash expense and should be added back to net income, while the write-off itself does not affect the cash flow.
Step-by-step explanation:
During 2014, when Osborn Corporation recorded a provision for bad debt expense of $75,000 and wrote off accounts receivable of $23,000, the correct calculation for the adjustment to net income in the net cash provided by operating activities using the indirect method would be option D. a $75,000 increase.
The provision for bad debts is a non-cash expense and would be added back to the net income when preparing the cash flow statement using the indirect method. The actual write-off of accounts receivable does not affect the cash flow, as it merely adjusts the accounts receivable and allowance for doubtful accounts on the balance sheet without any cash movement.
