The answer is house.
In the top row, each word is a type of light source. In the bottom row, each word is a type of shelter. The words in the bottom row are related to the words in the top row in the same way that a hut is related to a cottage. A hut is a small, simple shelter, while a cottage is a larger, more permanent shelter. Similarly, a candle is a small, simple light source, while a lamp is a larger, more permanent light source.
The other options are not correct because they are not related to the words in the top row in the same way. A tent is a temporary shelter, while a city is a permanent settlement. A dwelling is a general term for a place where people live, while a house is a specific type of dwelling.
