|This answer is wrong right is [A]. Stop and wait ARQ waits for positive or negative ACK from the receiving terminal if ACK is positive then after send a next block and ACK is negative re-transmit the same block.|

|A stop-and-wait ARQ sender sends one frame at a time; it is a special case of the general sliding window protocol with both transmit and receive window sizes equal to 1 and more than one respectively. After sending each frame, the sender doesn't send any further frames until it receives an acknowledgement (ACK) signal. After receiving a good frame, the receiver sends an ACK. If the ACK does not reach the sender before a certain time, known as the timeout, the sender sends the same frame again.
So, the answer should be A.

|The Answer is A because A stop-and-wait ARQ sender sends one frame at a time, After sending each frame, the sender doesn't send any further frames until it receives an acknowledgement (ACK) signal.|

|Yes, the answer must be A. The transmitter waits for the positive and negative acknowledgement after sending the block.|

|The answer should be A.
In a stop-and-wait ARQ system, the transmitting terminal waits for a positive or negative acknowledgement from the receiving terminal after sending a block.
