From the words lettered A to D, choose the word that best completes each of the following sentences:
Hardly had the family settled down for Mummy's special dinner............the lights went off

Answer Details

The correct option is "when". The sentence is expressing that the family had barely settled down for dinner when the lights went off. "When" is the most appropriate option to use in this context as it expresses the idea of a sudden occurrence happening at the same time or immediately after another action.
