In the sentence, identify the segment which contains the grammatical error. In the case of the guinea pig, the number of offsprings varies between two to five.

The grammatical error of the sentence is in option C. The error is related to the noun “offsprings”. Singular and plural versions of a few nouns are the same: offspring, deer, sheep, aircraft, apparatus, etc. are a few of them. For example, The airline is taking steps to ensure the safety of its aircraft. There were several sheep in my field. A lot of deer were brought to the zoo. ‘Offspring’ means ‘the young of an animal or humans’. For example, Ram’s sister came over on Sunday with all her offspring. Here, ‘offspring’ is a plural noun as it is written after the clause ‘the number of’. And we write singular verb (i.e. varies in this sentence) after this. In order to make the sentence correct, replace ‘offsprings’ with “offspring”. Correct sentence: ‘In the case of the guinea pig, the number of offspring varies between two to five.’
