Concerns for the environment have led chemists to develop plastics that are degradable. All degradable plastics, which are potentially useful packaging materials, need just the right conditions to break down. Some need exposure to sunlight, some need to be buried in soil, and some need to be submerged in water. It should be cautioned that some degradable plastics leave residues of unknown toxicity. If all of the statements above are true, which one of the following must also be true?

(A) Some materials that are potentially useful for packaging leave residues of unknown toxicity.

(B) Some degradable plastics need both sunlight and submersion in order to break down.

(C) Some materials that need sunlight in order to break down are not potentially useful packaging materials.

(D) Some materials that leave residues of unknown toxicity are not degradable plastics.

I blow big time on CR questions (Read: I am new to GMAT). I hope the answer I picked is correct. Somehow, I am unable to grasp that "magic trick" with CRs. Hopefully, I will be able to, sooner than later.

Done. A little tricky and I think all the must be true questions are supposed to be tricky.

Hope the answer is correct.
