Final answer:
In the sentence 'The manager told Jill and _______ to mark the sale items', the blank should be filled with the object pronoun 'us' to indicate that the speaker is included in the group being told to mark the sale items. The correct answer is option d.
Step-by-step explanation:
The correct word to complete the sentence "The manager told Jill and _______ to mark the sale items" is 'us'. This sentence requires an object pronoun because Jill and the speaker are the objects of the verb 'told'. The options given are 'he', 'she', 'them', and 'us'.
The choice of pronoun depends on whether the speaker is including himself or herself in the group being told to mark the sale items.
The pronouns 'he' and 'she' are subject pronouns and are not used as objects in a sentence.
'Them' could be a valid object pronoun if the speaker is not including themselves in the group, but since the question suggests that the speaker is part of the group, the correct pronoun is 'us'. Hence, the completed sentence should read: The manager told Jill and us to mark the sale items.
