Step 1: Plan an elimination route.
Instead of testing the four options one by one from the start, we first pick the pairs we are surest about. Each sure pair removes the options that disagree with it. We then confirm the survivor against the remaining pairs.
Step 2: Use pair A.
Santosh worked in the Neo-Tantric style and used symbols from Tantric philosophy. Hence A goes with II. This removes options 1 and 3 and 4. Options still alive: option 2.
Step 3: Use pair B.
Chittaprasad is famous for his famine pictures from Bengal. Hence B goes with I. No option is removed by this pair because every option still agrees with it. Options still alive: option 2.
Step 4: Use pair C.
Atul Dodiya uses photorealism in many paintings. Hence C goes with III. No option is removed by this pair because every option still agrees with it. Options still alive: option 2.
Step 5: Use pair D.
Vivan Sundaram is known for installation work. Hence D goes with IV. No option is removed by this pair because every option still agrees with it. Options still alive: option 2.
Step 6: Why each rejected option fails.
Option 1 fails at A (it says I, but II is the right partner), B (it says II, but I is the right partner).
Option 3 fails at A (it says IV, but II is the right partner), B (it says II, but I is the right partner), D (it says I, but IV is the right partner).
Option 4 fails at A (it says III, but II is the right partner), B (it says IV, but I is the right partner), C (it says I, but III is the right partner), D (it says II, but IV is the right partner).
Step 7: Confirm the survivor.
Only option 2 is left. Reading it against all four verified pairs, A-II, B-I, C-III, D-IV, shows a complete match. The other options each break at least one verified pair, so none of them can be correct.
Final Answer:
The only option that survives every check is option 2.
\[ \boxed{2} \]
