This question  perhaps was unpopular with the candidates.   Most candidates could not give a clear distinction between  commercialization and privatization in the (a) part.  The (b) part was even more difficult for the  candidates as only a few of them attempted it.
                    However,  candidates were expected to write the following points to score good marks in  this question.
                    (a) Privatization is the transfer  of ownership and control of a government owned    business to private individuals while commercialization is the efficient  running of a government enterprise with the major motive of making profit.
                    (b) Privatization
                    
                      - reduces government expenditure 
- promotes efficiency in the  running of businesses.
- promotes innovation.
-   promotes economic development.
- creates avenue for private investment. 
- provide government with short term revenue
-   reduces  the problems of corruption, nepotism, etc. associated with public                      corporations.
