    "Performed" is the right word.
  • 適当てきとうJLPT N4approx.Common
    na-adjective, nounIt can mean 'suitable, proper', but in many everyday uses it suggests something vague or done half-heartedly, so it is a risky choice for 'appropriate'; 適切 is usually safer.

    Can you please let me know the most suitable person in INF Co., Ltd?

    君きみにふさわしいはずはないのだから。↗
    He couldn't be good for you.
  • 当該とうがいCommon
    no-adjectiveBelongs to formal written and legal language: it means 'the ... in question' or 'concerned', as in the authorities concerned, and is seldom the word you want for 'appropriate' in ordinary contexts.
  • 相応そうおうJLPT N1approx.Common
    na-adjective, no-adjective, suru verb, intransitive verbDescribes something befitting or proportionate: conduct appropriate to a person's age or standing, or a price and reward that match the worth of what was done.
    収入しゅうにゅう相応そうおうの暮くらしをしなさい。↗
    Try to live within your means.

Use 適切 for the everyday sense of 'right for the situation', 「ふさわしい」 for what befits a person or occasion, 相応 for what is proportionate to someone's standing, 適当 with caution, and 当該 only in formal 'concerned' contexts.
