  • A. Ziegler–Natta catalysts chosen
    Ziegler–Natta catalysts are a class of organometallic catalysts used industrially to produce stereoregular polyolefins such as polyethylene and polypropylene under relatively mild conditions.
  • B. Wilkinson's catalyst
    Wilkinson's catalyst is a homogeneous rhodium-based coordination complex widely used in organometallic chemistry for the catalytic hydrogenation of alkenes.
  • C. Grubbs catalyst
    Grubbs catalyst is a family of ruthenium-based organometallic complexes widely used to catalyze olefin metathesis reactions in organic and polymer chemistry.
  • D. Adams catalyst
    Adams catalyst is a platinum-based hydrogenation catalyst widely used in organic chemistry for reducing a variety of functional groups under mild conditions.
  • E. Trost ligand
    The Trost ligand is a chiral diphosphine ligand widely used in palladium-catalyzed asymmetric reactions, particularly for achieving high enantioselectivity in allylic alkylation.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
