Which sentence does not maintain a consistent point of view

1. i walked out of the mall. i was out of money and had to call my mom.

2. shelley walked out of the mall. she was out of money and had to call her mom.

3. sam walked out of the mall he was out of money and had to call his mom.

4. shelley thought about what to buy. i was out of money and had to call my mom.

The sentence that does not maintain a consistent point of view is 4. Shelley thought about what to buy. I was out of money and had to call my mom.

The point of view is the narrator or the person about whom the information refers to. In sentence four, Shelley is mentioned first and then it changes the focus to the first person singular "I".

The other options are consistent because option 1 is told from the first person singular "I", option 2 is told from the point of view of Shelley and option 3 is told from the point of view of Sam.
