Step 1: Understand the question:
The question needs the artists who worked in printmaking. Three of the four fit and one does not.
Step 2: Find the painter:
S. H. Raza of the Progressive Artists' Group worked mainly as a painter. So C is the outsider.
Step 3: Use the options:
Options 2, 3 and 4 all include C. Option 1 is the only one that leaves C out.
Step 4: Confirm the rest:
Chittoprasad and Somnath Hore used linocut and woodcut for social subjects. Krishna Reddy was a world-known printmaker. So A, B and D stand.
Final Answer:
Leaving out the painter Raza gives A, B and D, so option 1 is correct.
\[ \boxed{\text{Option 1}} \]
