Understanding the Concept:
This is a recall question about the subject of the painting, not a calculation. We combine the mood of the image with the artist's known themes.
Step 1: Mood of the painting:
The scene looks like a fantasy city seen at night, with light that does not come from any natural source. It feels like a lost or hidden city.
Step 2: Think of legends:
A lost city of legend in the options is Dwarka, said to have been built by Krishna and swallowed by the sea. The other three are known living cities.
Step 3: Link to the painter:
Gaganendranath Tagore made a set of imaginary city paintings, and Dwarka is the one commonly cited in textbooks.
Step 4: Conclude:
Hence option 1. The match is based on recall, so confirm it against the textbook caption if possible.
Final Answer:
Option 1 is correct. \[ \boxed{\text{Dwarka}} \]
