Concept:Both reasons independently explain why people queued at payment counters on 14th June 2023.
Explanation:The deadline for electricity bill payment is the 15th of every month.
So on the 14th, people rush to pay before the deadline to avoid late fees.
This makes Reason 1 correct.
Server failure in June 2023 stopped many people from paying bills online.
As a result, they had to visit the payment counters in person.
This makes Reason 2 correct.
Thus, both reasons together fully justify the long queues observed.
Answer:Both 1 and 2 are the correct reasons.
Hence, the correct option is Option B.
