apologies vs. apology

[Rickyrocky]

Hi,

My apology for the error.
vs.
My apologies for the error.

Please accept my apology.
vs.
Please accept my apologies.

Which of the sentences is correct and why?

Thanks.

HI,

The plural form just tends to make the regret you are expressing slightly more formal. The expression 'Present his/her/their apologies' is used in a very formal sense when you interrupt a meeting or discussion and deliver a message on behalf of another person.

Hi, teacher!

When I should use the word 'apology' and 'apologies'?

Please explain the difference. Thank you very much : )
