1. someone 2. stolen 3. watch 4. has 5. my A. 12543 B. 14253 C. 12345 D. 12534

The correct answer is D. 12534.

The first word, “someone,” is the subject of the sentence. The second word, “stolen,” is the past participle of the verb “to steal.” The third word, “watch,” is the direct object of the verb “to steal.” The fourth word, “has,” is the present tense of the verb “to have.” The fifth word, “my,” is a possessive pronoun.

The sentence can be paraphrased as follows: “Someone has stolen my watch.”

The other options are incorrect because they do not form a grammatically correct sentence.
