Select the option that expresses the given sentence in active voice.
I am upset because my cell phone has been stolen.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. I am upset because someone has stolen my cell phone.
The original sentence is in passive voice: 'my cell phone has been stolen.'
To change it into active voice, we need to identify a doer (someone) performing the action.
Option 2 correctly uses the present perfect tense in active voice: 'someone has stolen my cell phone.'
Option 1 is in present perfect continuous ('has been stealing'), which changes the meaning to an ongoing action.
Option 3 changes the tense and meaning by using 'I have been upset,' which is different from the original.
Option 4 uses past tense ('was upset') and 'they have stolen,' mixing tenses incorrectly.
