Final answer:
The correct completion for the sentence 'The cattle ____ in the field every day' is 'graze', as it correctly maintains the subject-verb agreement with the plural noun 'cattle'.
Step-by-step explanation:
The correct answer to this question is option C, 'graze'. The subject of the sentence, 'cattle', is plural, so the verb should also be in plural form to maintain subject-verb agreement. So, the verb 'graze' fits the best. Options A and D use the singular form 'grazed' and 'grazes', which does not match with the plural subject 'cattle'. Option B 'are grazing' is in present continuous form and doesn't seem to best fit this context, as we're discussing a general, repeated everyday event, not a specific event happening right now.
