From the words or groups of words lettered A to D, chose the word or group of words that best completes the sentence.
The party had hardly started...the lights went off.

Answer Details

The correct option is "when". In this sentence, "when" is the most appropriate conjunction to use because it connects the two events in the sentence and indicates the time relationship between them. It shows that the lights went off at the moment the party had hardly started. Therefore, the sentence should read: "The party had hardly started when the lights went off."
