Choose the correct spelling from the options given below:

a)interrogation
b)interogetion
c)interogation
d)interagation

Hint: The phonetic sound usually helps to match the spelling with the word.

Complete step-by-step answer:

 The given word can be guessed. It is pronounced as in-ter-row-gae-shun. Making an approximation of the sound will help to guess the spelling.

Now, let’s look at our options:

a)interrogation - This word completely matches the phonetic sound of the given word. It aligns with the sound and is grammatically correct. So, this is the correct option.
b)interogetion - This word does not contain a double ‘r’, which will affect the sound of the word. The middle part of the word also is wrong, as it would be pronounced as a short ‘ga’ sound. It is grammatically incorrect. So, this is an incorrect option.
c)interogation - This word also does not contain a double ‘r’, which will affect the pronunciation of the word. The sound will not be dragged out more. This option is also grammatically incorrect. So, this is an incorrect option.
d)interagation - The middle part of this word contains the syllable ‘ga’ which would produce an incorrect sound. This spelling is grammatically incorrect, too. So, this is an incorrect option.
