Fill in the blank using a suitable option:
She was joyful _____ seeing her child take his first steps.

• A. upon
• B. with
  
• C. in
  
• D. over
• E. to
  

Answer 1

The correct option is A upon

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option A)upon is correct as it is used formally to indicate a surface. The other options are wrong as with is used to indicate inclusion, in is used to indicate a position in an area, over is used to indicate a higher position and to is used to give a direction. These uses don't fit in the given question. The correct answer is A) upon.
