Answer 2

John used D. Smothering

By placing plastic over the plants, they wouldn't be able to receive sunlight and thus they starved because plants don't only live off of water and soil nutrients, they also need sunlight for a process called photosynthesis that helps them make food out of water and carbon dioxide.
