The World Bank, the only one of its kind,
provides loans to developing member countries, gives technical assistance for development projects, and for projects from other public and private sources encourages co-financing. A. provides loans to developing member countries, gives technical assistance for development projects, and for projects from other public and private sources encourages co-financing. (Correct construction would be X,Y, and Z to maintain the parallelism,comma after projects is not correct,comma before encourages is required)
B. provides loans to developing member countries, gives technical assistance for development projects, and for projects from other public and private sources encouraging co-financing. (same as in A,encouraging is incorrectly modifying sources)
C. provides loans to developing member countries, gives technical assistance for development projects, and for projects from other public and private sources encouraged co-financing.(same as in A,encouraged is incorrectly modifying sources)
D. provides loans to developing member countries, gives technical assistance for development projects, and encourages cofinancing for projects from other public and private sources.(correct,maintains parallelism)
E. provides loans to developing member countries, gives technical assistance for development projects, but encourages cofinancing for projects from other public and private sources.(but changes the meaning,and is required)
I will go with option D.
Thanks
