Grammar

In this sentence, "The accountant and cashier" refers to two people, so the plural form "have" is correct. "Has" would be incorrect because it is singular. "Had" and "will have" are not appropriate in this context.

The correct passive construction for this imperative sentence is "Let your work be done honestly," as it retains the imperative tone but shifts to the passive voice. Thus, the correct answer is "Let your work be done honestly."

The correct form for indirect speech here involves changing "will" to "would" and removing the direct quotation marks. Option (3) is the best expression. Thus, the correct answer is "I told you that she would give you my pen next day."

The superlative form "best" is used here because the sentence implies that Mohan is the most significant or most outstanding friend of the speaker. "Better" would not be appropriate as it's a comparative form. Thus, the correct answer is "best."

The sentence talks about a completed action that took place in 2005, so the correct past tense of the verb "pass" is "passed." Thus, the correct answer is "passed."

Since "Bacon and eggs" refers to two items (plural), the verb "are" is the correct choice for the present tense in this sentence. Thus, the correct answer is "are."
