Question

fill in the blanks using suitable prepositions​

Answer 1

Answer:

We can determine the correct answer with the help of logic and by eliminating the incorrect answer.

The first blank of the sentence indicates her activity. 'For' and 'on' does not fit correctly in the sentence as these prepositions do no indicate one's activity. We can thus eliminate options A and B as incorrect answers.

At is used to indicate a point of time or place, state, direction. age or occupation, degree and one's activity. Here the preposition 'at' fulfills the meaning of both the blanks. Thus option C is the correct answer.
