I suggest that the meeting . . . . . . . . postponed.

The correct answer is: B. would be

The sentence “I suggest that the meeting would be postponed” is in the subjunctive mood. The subjunctive mood is used to express wishes, possibilities, and recommendations. In this case, the speaker is recommending that the meeting be postponed.

The other options are incorrect because they are not in the subjunctive mood. Option A, “is,” is in the indicative mood, which is used to state facts. Option C, “be,” is also in the indicative mood. Option D, “was,” is in the past tense, which is not appropriate for this sentence.

Here are some more examples of the subjunctive mood:

• I wish I were rich.
• It is important that you be on time.
• I suggest that we go to the movies.
• I demand that you apologize.
