Explanation:

• International Comparison Program is the largest worldwide data-collection initiative, under the guidance of UN Statistical Commission (UNSC), with the goal of producing Purchasing Power Parities (PPPs) which are vital for converting measures of economic activities to be comparable across economies.
• Along with the PPPs, the ICP also produces Price Level Indices (PLI) and other regionally comparable aggregates of GDP expenditure.
• The Ministry of Statistics and Programme Implementation is the National Implementing Agency (NIA) for India, which has the responsibility of planning, coordinating and implementing national ICP activities.
• India was also a co-chair of the ICP Governing Board along with Statistics Austria for the ICP 2017 cycle. Hence only statements 1&2 are correct.
