Concept:
- These four buildings can be separated by one feature each, a dome, a scale-like plan, a plain office block and a triangle.
- Matching the single most striking feature of the picture to that list settles the answer.
Step 1: Pick the most striking feature in the picture.
The plan of the building is triangular. That is unusual and immediately narrows the search, since only one major building in the capital is built on a triangular plan.
Step 2: Match each option with its signature feature.
Rashtrapati Bhavan is remembered by its dome, the Supreme Court by its scales-of-justice layout, and Nirvachan Sadan by nothing distinctive at all, being a working office of the Election Commission.
Step 3: Use the clue in the background.
A circular building with a statue on top is visible behind the triangular one. That circular building is the old Parliament House, and the two stand side by side in the same complex.
Step 4: Draw the conclusion.
A triangular building standing beside the old circular Parliament House can only be the new Parliament House of India.
Final Answer: (C) Parliament of India
