I am not a chemistry person. But I was doing a course on organic solar cell and I cannot pass the test as I am stuck on two questions which I had thought to be simple but they are not. I will ask just one question here which says "Which of the following polymers is a conjugated polymer?" (multiple answers correct)

Thanks a lot!

Here are my attempts in failing the quiz!

Only two of those, as written, are what I'd consider "polymers", never-mind whether or not they are conjugated.

What is the definition of a polymer? And what distinguishes a conjugated polymer from a non-conjugated polymer?

I am really not a chemistry person!
I have no idea of this question.

[Corribus]

But you are taking a quiz/test on this material, so surely it must have been covered in your coursework. If you do not have the proper background to understand course materials, this is something you need to discuss with your professor, as it will likely only get worse.

shirpa:, I've locked this question, because I don't see it going anywhere productive.  Please read and comply with the Forum Rules{click}, we want to see your attempt.  What is the reason behind what you did?

Please try to attach the images to the thread, so we can do what you have to do: quickly look at the images, all together, and make decisions.  Please tells us what you did, the answer doesn't need to be an image, and not an empty white box.  And then, we'll tell you, where your reasoning is incorrect, and how you can improve. 

All you've done, three times, is say you're not a chemistry person.  But Corribus: points out --  you want credit for a chemistry course?  And a job using these concepts possibly?  If you don't stop behaving that way, no one will want to even work next to you, never mind helping you.
