Communication Services

Correct answer: A, the receiver’s response, opinion, or signal about a message. In a communication process, the sender creates and sends a message, while the receiver receives and interprets it. Feedback is what the receiver communicates back after or while understanding the message. It may be a spoken reply, written answer, question, nod, facial expression, or another meaningful signal. Feedback helps the sender know whether the message was understood, accepted, misunderstood, or in need of clarification. B is not feedback because hiding prevents a response. C ignores the receiver and therefore removes an important part of two-way communication. D ends or blocks communication rather than responding to it. Feedback need not always be agreement; even a question can show that the receiver is engaged but needs more explanation. Memory cue: feedback travels back from receiver to sender.

Correct answer: A, the person or organisation that sends the message. Communication begins when a sender has an idea, purpose, or information to share. The sender converts that idea into understandable words, symbols, images, or other forms and transmits the message through a suitable channel. B is the receiver, whose role is to obtain and interpret the message. C is the channel or medium, such as a telephone, letter, email, or conversation; a medium carries the message but does not originate it. D describes noise or a communication barrier, which can distort, delay, or block the message. A sender may be an individual, group, institution, or business. Identifying the roles prevents confusion: sender sends, receiver receives, channel carries, and noise interferes. Memory cue: the sender starts the message; the receiver makes sense of it.

Patient listening helps identify the customer’s actual concern, while clear and accurate information supports an appropriate solution and builds trust. Information should be checked before it is given, and promises should be realistic. Rudeness, incomplete answers, and impossible commitments damage service quality, so option A is the best practice.
