<p>The correct answer is <strong>(A) will be held</strong>.</p>
<p>In this sentence, we are talking about a future event - the Opening ceremony of the games that will happen on 27 July 2024. When we talk about future events that are planned or scheduled, we use the future tense with "will".</p>
<p>The verb "hold" means to have or organize an event, so option (B) "will hold" seems like a possible choice. However, in English, we usually use the passive voice when talking about events or ceremonies being held. Therefore, the correct form is "will be held".</p>
<p>Options (C) "will take" and (D) "will be taken" are incorrect because they do not convey the idea of an event being organized or held. Instead, they suggest that something will happen to the Opening ceremony or the games, which is not the intended meaning.</p>
