The question doesn’t mention the excerpt. However, the second paragraph from the first chapter of Great Expectations is most likely what the question talks about, which is:
“As I never saw my father or my mother, and never saw any likeness of either of them (for their days were long before the days of photographs), my first fancies regarding what they were like were unreasonably derived from their tombstones.”
Answer:
Picture
Step-by-step explanation:
It is self-evident from the mention of the word “photographs” from the above line that the word “likeness” refers to a ‘picture’, meaning that Pip, the protagonist and narrator, had never seen a picture of his parents as they didn't have photographs during their time, and all his imagination as to what they looked like were derived from how their tombstones looked like.
One of the dictionary meanings of likeness in general also is "a portrait or representation," which relates to its usage here.
