The question "Which is R's favorite city?" likely refers to the programming language R, which was developed in New Zealand and has a strong user community in various parts of the world, including India. Among the provided options—Mumbai, Delhi, Hyderabad, and Pune—Delhi is often considered a hub for data science and statistical research in India. The city hosts numerous universities, research institutions, and technology companies that focus on data analytics, biostatistics, and related fields where R is widely used.

Moreover, Delhi's vibrant academic environment and its proximity to prominent institutions such as the Indian Statistical Institute and various Indian Institutes of Technology (IITs) make it a focal point for R programming professionals and enthusiasts. While each of the listed cities has its own merits and contributions to the field, Delhi stands out as a central location for the R community in India, which might explain why it is humorously suggested as "R's favorite city."

Thus, the underlying rationale for selecting option B, Delhi, as the correct answer hinges upon its importance in the context of R programming and data analysis.
