Was waving
You can say it like:
"Every man was waving a flag"
"Every woman was waving a flag"
"Every child was waving a flag"
It also makes sense to say it in present tense
"Every man is waving a flag"
"Every woman is waving a flag"
It wouldn't make sense to say:
"Every man are waving a flag"
"Every man be waving a flag"
What is the subject? I won't be able to help you unless I know what the subject is. Also, is there a passage you could provide?
Thank you
Henry's style of combat towards the end of the book can be best described as…

~Hope this answers your question!~
Your answer would be A. I was just doing this. So if you read up to the comma it is a complete sentence by itself.
