Week 4 - Graded Quiz - Question 5 - Answer is wrong

Select all the options that are a basis for the 3D space
2 options are true while 2 options are false however the 5th option keeps answering differently depending on how you answer: ex. “You didn’t select all the correct answers”
I cannot show the 5th option (no code allowed), but the 3 vectors are not linearly independent.
Thank you for your consideration.

It’s a bit hard to say anything here without seeing the actual details, which (as you rightly say) we aren’t supposed to do on a public thread. Thank you for respecting the rules, but I will send up a private message where we can discuss in more detail.
