Select the most appropriate option that rectifies the incorrectly spelt word…

In a “find the correctly spelt word” item, exactly one word in the given sentence is misspelt; the task is to locate that word and choose the option that gives its standard English spelling, while the remaining options are alternative spellings of words that are already spelt correctly in the sentence.

1. army — already spelt correctly; it is not one of the four options.

2. threatened — already spelt correctly as t-h-r-e-a-t-e-n-e-d; it does not need correcting.

3. anihilate — as written this omits a letter; the standard spelling is a-n-n-i-h-i-l-a-t-e, with a doubled n after the initial a, so this is the word that is misspelt in the sentence.

4. entire, city, block, rebels, refused, surrender — each is already spelt correctly in the sentence (surrender takes a doubled r: s-u-r-r-e-n-d-e-r).

Checking each option against the sentence: “entire” already appears correctly, so “antire” does not correct a real error; “threatened” already appears correctly, so “threathned” does not correct a real error; “surrender” already appears correctly, so “surrander” does not correct a real error. Only “anihilate” is an actual misspelling in the sentence, and “annihilate” is its standard spelling.

Hence, the word that needs correcting is “anihilate”, and its correct spelling is annihilate.
