Good Morning,

the third issue is wrong as indicated into the comment but the green highlight appears just onto this answer. I downloaded and updated the "etsviewer.jar" on 19th April 2021. Thanks for your support. Have a good day and a good work.

Options 1 2 and 3 are correct (that is why they are highlighted in green) because the problem statement asks, "Which of the following lines of code may throw a NullPointerException in certain situations?"
