<p>The correct answer is <strong>(B) departs</strong>.</p>
<p>In this sentence, we are talking about a ferry that is scheduled to leave from Waterfront at 9:00 A.M. Since we are referring to a single ferry, we need to use the third person singular form of the verb "depart". Therefore, the correct form is "departs".</p>
<p>Option (A) "depart" is incorrect because it is not the correct verb form for the subject "ferry".</p>
<p>Option (C) "is departed" is incorrect because it uses the passive voice, which is not appropriate in this context. We are more interested in the action of the ferry leaving rather than who or what is performing the action.</p>
<p>Option (D) "has been departed" is incorrect because it uses the present perfect tense, which is not appropriate in this context. The present perfect tense is used to describe actions that happened in the past and have a connection to the present, but in this sentence, we are only talking about a single future action.</p>
