<p>Had the marketing department submitted the sales report on schedule, the manager <u>would not have had</u> to cancel the meeting with the CEO.</p>
<p>The correct answer is (D) <u>would not have had</u>.</p>
<p>In the sentence, the phrase "Had the marketing department submitted the sales report on schedule" introduces a hypothetical situation or a condition that did not actually happen. This is called the subjunctive mood. When using the subjunctive mood, we use the past perfect tense to indicate an unreal or hypothetical condition in the past.</p>
<p>In this case, the verb "to have" is conjugated in the past perfect tense, "had." However, because the condition is hypothetical and did not happen, we use the negative form "would not have had" to indicate that the manager did not need to cancel the meeting because the sales report was not submitted on schedule.</p>
<p>Therefore, the correct answer is (D) <u>would not have had</u>.</p>
