Question

myself and the team have worked long hours on the project.
correct incorrect

Explanation:

In standard English, when a pronoun is part of the subject of a sentence, the nominative (subjective) form should be used. "Myself" is a reflexive pronoun, which is not appropriate for the subject position here. The correct subject pronoun is "I", so the sentence should be "I and the team have worked long hours on the project" (or more naturally, "The team and I have worked long hours on the project").

Answer:

incorrect
