Answer:
a. $200 decrease in net income.
Step-by-step explanation:
When insurance is paid in advance, the entries required are;
Debit Prepaid Insurance
Credit Cash account
As time elapses and the insurance expires,
Debit Insurance expense
Credit Prepaid Insurance
Given that the Adjustments columns show expired insurance of $200, this will be recorded as an expense and will thus decrease the net income.
