    Answer is 1 .
    If you clearly observe the question: He asks for a di-acid. So essentially, there must be two "-COOH" groups in the product. That narrows down the answer from various chemical compounds used in the reaction.
    If you check the by-product the COOH's are present in the meta position of the Benzene ring.

    So the answer would be A) IsoPhthalic acid.

    Good luck mate :)

    Did you already try the black hat way?

    I.e. mailing http://www.thaipolyester.com/ and asking them whether their by-products are safe for environment? Then slowly proceeding to structure of diacid monomers, and finally becoming an affiliate? :)
