Explanations:The question asks about the duration of Saheb's family's residence in Delhi. To understand this, it is important to consider the historical context and the typical duration of family residence in a city like Delhi. Delhi has a rich and long history, and families often have deep roots in the city that span several generations.
When evaluating the options, it is crucial to consider the historical timeline and the typical duration of family residence. The options provided are 25 years, 45 years, 10 years, and 30 years. The correct answer is 30 years, as it fits the historical context and the typical duration of family residence in Delhi.
Option A (25 years) is too short for the context of the question. Families in Delhi often have a longer history in the city than 25 years. Option B (45 years) is longer than the correct answer, and while it is possible for a family to have lived in Delhi for 45 years, the question specifies "more than" a certain number of years, and 30 years is the correct duration. Option C (10 years) is far too short for the context of the question, as it is unlikely that a family would be considered to have lived in Delhi for more than 10 years in the context of historical residence.
The correct answer, 30 years, fits the historical context and the typical duration of family residence in Delhi. This duration is long enough to be considered a significant period of residence, but not so long as to be unrealistic or improbable. It is important to understand the historical timeline and the typical duration of family residence in a city like Delhi to correctly answer this type of question.
