Given that a credit to an asset account was posted to an expense account.
We know that debit all comes in and credit all goes out for asset account
When asset account has to be credited there is a sale of asset and hence asset has to be reduced in value.
If wrongly posted to expenses account, then expenses would be credited by that amount. This will give assets a higher value and expenses a lower value.
When expenses are lower, profits high and hence capital would be ovestated.
I'm not entirly sure, but i'm pretty sure that since the number line is coming form the left side that makes it negative. It stops on two and it's shaded in so D would be the correct answer.
