The answer is "A) Bank Teller".
A bank teller (frequently abbreviated to just teller) is a worker of a bank who bargains specifically with clients. In a few places, this worker is known as a clerk or client representative. Most teller employments require involvement with dealing with money and a secondary school confirmation. Most banks give hands on preparing.
Tellers are considered a "front line" in the keeping money business since they are the principal individuals who a client sees at the bank.
