@Autowired
private RabbitTemplate rabbitTemplate;

public void sendMessage() {
    rabbitTemplate.convertAndSend("", "myQueue", "Hello");
}

ANo error, code is correct

BEmpty exchange name is invalid

CconvertAndSend requires routing key, not queue name

DMethod should return a value

Step-by-Step Solution

Solution:

Step 1: Check exchange parameter
convertAndSend("", "myQueue", "Hello") uses empty string "" for exchange, which refers to the default exchange. Valid.
Step 2: Verify routing key usage
"myQueue" as routing key with default exchange correctly sends to queue "myQueue".
Step 3: Confirm no other issues
@Autowired, method signature, and syntax are correct. No mistakes.
Final Answer:
No error, code is correct -> Option A
Quick Check:
Empty exchange means default exchange and is valid [OK]

Quick Trick: Empty exchange means default exchange, valid usage [OK]
