b) These
c) This
d) It

Answer 1

Hint: The pronouns given in the options are demonstrative pronouns. These words are used to indicate which entities are being referred to and to distinguish those entities from others.

Complete answer:
The demonstrative pronouns are typically deictic; their meaning depending on a particular frame of reference and cannot be understood without context. For example This, that, these, there, etc. In the given question we have to fill in the blank with the correct demonstrative preposition.
Now, let us examine all the given options to find out the correct answer :
Option ‘a' is That. This is used for singular and countable things. It forms a subject, object, or complement of the relative clause. For example It’s a song that my mother taught me.
Option ‘b’ is These. It is used with plural and countable things. It is the plural of ‘this’. For example These mangoes are so delicious.
Option ‘c’ is This. It is used for singular words. It takes the place of a noun or noun phrase. For example This is my room.
Option ‘d’ is It. It is used for a thing previously mentioned or easily identified. It also serves as a placeholder subject in sentences with no identifiable actor.
As we have analyzed all the given options, we can easily figure out the correct answer. Here, the correct demonstrative pronoun to be filled in the blank is – these. The complete sentence would be – These birds have colourful wings. Hence, option ‘b’ is the correct option.

Note:
Pay attention to the noun in the given sentence. It is clearly mentioned in plural form. It is “birds”, so only ‘these’ can be filled in the given blank.
