D) Roger should have practiced more if he wanted to win the tournament.
Explanation:
Subjective is nearly an opinion, is not a fact or cannot be confirmed. A is unlikely to be the answer. Although the coaches are stating an opinion, the sentence is not using words that would state an opinion (think, believe, etc.). B is also stating a fact. C is not possible, because it is stating a fact.
