In the following question, the sentence with blank is to be filled with appropriate word. Select the correct alternative out of the four and indicate it by selecting the appropriate option.
Previously, she was one of the three Deputy Director-Generals supporting the Director-General in ________ all programmes.
Option 3 is the correct answer because, 'overseeing' means 'supervising (a person or their work), especially in an official capacity'. The verb 'supporting' suggests that the next verb must also be in progressive form to form the parallelism.
Let us take an example to understand it better:
Option 1 is wrong because, first form of verb is given which doesn't form a balance with the verb 'supporting'.
Option 2 is wrong because, participle form is given.
Option 4 is wrong because, second form of verb is given.
