Explanation:

A hyphen is a punctuation mark used to join two words together in order to create a new meaning or a combined meaning, join a prefix to another word or show word breaks.

“Self-assured” is a compounded word joined by a hyphen. It is formed by a noun and an adjective. These words when put together mean to be sure of oneself.

“Resign” in this sense means to quit or give up one's job position.

“Re-sign” is a compound word joined by a hyphen. It is formed by the prefix “re” (which indicates repetition), and the verb “sign.” As a whole, this word means “to sign again.”

“Allegations” is a noun used to refer to an assertion especially of misconduct.
