Explanation:

There is nothing common between WPI and IIP as per the options.
The Wholesale Price Index (WPI) is the price of a representative basket of wholesale goods. Some countries (like the Philippines) use WPI changes as a central measure of inflation.But now India has adopted new CPI to measure inflation.
The Index of Industrial Production (IIP) is an index for India which details out the growth of various sectors in an economy such as mining, electricity and manufacturing.
