Should I Respond To Emails Without Links Seeking to Confirm My Email Address

I just received this email. What are the red flags of this email asking you to confirm a message from Pam coming from a Gmail account named anthony......@gmail.com?
a) The email address looks bogus
b) It’s unexpected and a prior email it refers to was never sent
c) It’s probably a bot or social engineering scam looking to confirm active email accounts
d) all of the above
