- DI regret to inform you that I shall be unable to attend owing to a prior engagement.
Талдау
A written reply to a company director requires a formal register throughout. 'I regret to inform you that I shall be unable to attend owing to a prior engagement' uses formal phrases (regret to inform, shall, owing to, prior engagement) and has no colloquial elements. 'I regret to inform you that I can't come, 'cause I'm totally swamped with work right now' mixes a formal opening with the contraction 'can't', the slang 'cause' and the informal 'totally swamped'. 'Thanks a bunch for the invitation, but I am obliged to decline it, mate, as I am busy' mixes the informal 'Thanks a bunch' and 'mate' with the formal 'I am obliged to decline'. 'Sorry, no way I can make it to the conference, as I have a prior engagement, you know' is colloquial ('no way', 'you know') and unsuitable for a director. So only the consistently formal sentence is correct.
