Best answer 48 48 votes Answer is (C) Sender/Client send mail from client mailbox to server mail box with the help of $\textsf{SMTP}$ protocol whereas Receiver or Server retrieve the mail from its mail box to reading using $\textsf{POP3}$ protocol. When we want to take the help of process to see email in browser in that case we use $\textsf{HTTP}$. Because It creates beautiful page of mailbox with the help of process.
