She is . . . . . . . . for the final round of the competition.

declared
decided
qualified
superior

The correct answer is C. qualified.

The other options are incorrect because:

  • A. declared is not the correct word to use in this context. She has not been declared for the final round, she has qualified for it.
  • B. decided is not the correct word to use in this context. She has not decided to compete in the final round, she has qualified for it.
  • D. superior is not the correct word to use in this context. She is not superior to the other competitors, she has simply qualified for the final round.

To qualify for something means to meet the necessary requirements. In this case, she has met the necessary requirements to compete in the final round of the competition.
