i dont quite understand what resonance is, but ive worked out a,b,d,e, and out of those i think a is resonance. am i correct out of those four. also can someone help exaplain the question overall?

At one level, all compounds display resonance, so in that regard you are not right. However, on a simpler level, if you just look at moving electron pairs or similar around whilst maintaining the basic structure of a compound then you are also not correct.

Can you draw the resonance hybrids you have discovered for chlorine dioxide, and explain why similar things do not occur with the other 3 structures you have worked on so far?
