Final answer:
In business writing, 'First and foremost', 'Good to go', and 'Below the belt' are considered cliches and should be avoided for professionalism and clarity. 'Best regards' is not a cliche and is an accepted formal sign-off in business communications.
Explanation:
In the context of business writing and communication, cliches are phrases or expressions which are overused to the point where they lose their original meaning or novelty. It's ideally good practice to exclude them from your writing to maintain professionalism and clarity. The examples mentioned in your question, 'First and foremost', 'Good to go', and 'Below the belt', are indeed cliches and should be avoided in business communication. However, 'Best regards' is a formal and professional phrase which is widely accepted in business letters and emails as a sign-off line and is not considered a cliche.
