Final answer:
The suitable word for completing the sentence is 'inopportune', as it refers to something happening at an inappropriate or bad time.
Step-by-step explanation:
In this context, between officious and inopportune, the most suitable word to complete the sentence would be inopportune. The word officious describes a person who offers unwanted help or service, usually in a manner that is overbearing or interfering. In contrast, inopportune refers to something happening at a particularly bad time, such as a suggestion to spend money when one is financially strained. Thus the sentence can be completed as 'Coming at a time when I was flat broke, your suggestion that we have a bit to eat and go the movies was highly inopportune.'
