Phrase: heterogeneous Ziegler–Natta catalyst | Statement: [Ziegler–Natta catalysts, hasType, heterogeneous Ziegler–Natta catalyst]

Target entity: heterogeneous Ziegler–Natta catalyst
Context triple: [Ziegler–Natta catalysts, hasType, heterogeneous Ziegler–Natta catalyst]

• 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. Noyori asymmetric hydrogenation catalysts
  Noyori asymmetric hydrogenation catalysts are highly efficient chiral ruthenium complexes that enable enantioselective hydrogenation of ketones and related substrates, revolutionizing asymmetric synthesis in organic chemistry.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
