Which themes distinguish literature written in the realist era from earlier literature?

The theme would be

A. everyday life and common subjects

Explanation:

Artists and writers throughout realist era like to produce one thing that represents a pure state of affairs in truth, while not adding any false/extreme narrative to draw in attention or any supernatural part.

So, most of their works revolve around everyday life and also the issues that standard individuals expertise.

the narrator is saying that the old lady made her feel uncomfortable. you know this because they say "i found that rather irksome", "perhaps it was her being so upright and trim", and "i don't think it was that, because i thought that quaintly pleasant." hope this !
