Final answer:
Accommodation is available for all visiting guests. This indicates that there is space or rooms ready for guests to use.
So, the correct answer is B.
Step-by-step explanation:
The correct word to complete the sentence ‘Accommodation is ----------- for all visiting guests.’ is ‘available.’ When we say that accommodation is available, we are indicating that there is space or rooms ready for guests to use. The other options do not fit the context as well as ‘available’ does. Being ‘vacant’ would imply that accommodations are empty, but doesn’t necessarily mean they are ready for guests. ‘Engaged’ would typically mean taken or in use, which would be the opposite of what the sentence intends to convey. Lastly, ‘disposed’ means to get rid of something and does not relate to the context of providing accommodations to guests at all.
So, the correct answer is B.
