Question

Fill in the blank with the most appropriate word;
What’s _____ TV tonight?
A) In
B) At
C) On
D) By

Answer 1

Hint: The words given in the options are all prepositions, which are words indicating the position of nouns and pronouns, or expression of the relation of nouns/pronouns with other figures of speech. For e.g. I have an appointment with the doctor. ‘With’ is the preposition here.

Complete answer:
We already know that we need a preposition to fill the blank. Now we have to choose the appropriate one. For that, we need to know that there are different prepositions that are used for indicating people, places and events. In this case, we have an event or a TV program that has to be indicated.

Now let us look into the explanation of the given options:
Option A) In – This preposition indicates the position or location of a noun within some confined limits. For e.g. New Delhi is in India. It is not the appropriate option for filling the blank.
Option B) At – This preposition indicates the presence or occurrence of something in, on or near something else. For e.g. He was standing at the cash counter. This option also does not fill the blank correctly.
Option C) On – This preposition indicates the location or the position of a noun located on the top surface of something. For e.g. The helicopter landed on the roof of my house. ‘On’ is also used to indicate the medium of expression. For e.g. I heard her on the radio. This preposition is appropriate and hence, the correct option.
Option D) By – This preposition is used to indicate proximity. For e.g. She was standing by the window. It is also used to refer to a time period before a given time. For e.g. I’ll be there by noon. Thus, it is a wrong option.

Thus, the correct answer is option (C) What’s on TV tonight?

Note: The preposition ‘On’ has many other uses. It is used to indicate participation or involvement in something. For e.g. I went on a business trip. It is also used to indicate the subject being discussed. For e.g. I wrote a book on reptiles. We had an argument on who should publish the book.
