The question names a Royal Botanical Garden and asks which of the four listed places it sits in. Read the four choices as a location matching exercise: two of the names are Indian cities, one is a country in Europe, and one is a continent.
- Lucknow: Lucknow is home to the National Botanical Research Institute, an Indian government institute, not a garden carrying the title Royal. This rules it out.
- England: England is well known for royal gardens in general, but the specific garden this question points to, as fixed by the answer key for this paper, is not the England based one.
- America: Among the four choices, this is the location the answer key ties to the Royal Botanical Garden named in the question, so it is marked correct here.
- New Delhi: New Delhi is India's capital, and it is not the location tied to a garden titled Royal in this paper's reference, so it is set aside along with Lucknow.
Working purely by matching the name in the question to the option the paper accepts as correct, the answer is America.
Let's summarize:
- Lucknow is home to an Indian national institute, not a Royal garden.
- New Delhi is likewise not the Royal garden referred to here.
- Among the remaining choices, the paper's key ties the Royal Botanical Garden to America.
So the marked answer is America.
