type of catalyst selectivity

A group of scientists proposed the reaction pathway shown in Figure Q2 for the hydrodeoxygenation of m-cresol. They used a series of 3 heterogeneous catalysts to evaluate the proposed mechanism and the performance of the catalysts. The description of the catalysts are as follows: Catalyst A: 1% Pt supported on conventional microporous ZSM-5 Catalyst B: 1% Pt supported on micro-mesoporous ZSM-5 Catalyst C: 1% Pt supported on micro-mesoporous ZSM-5 The catalysts are synthesised in way that the Si/Al ratio of the zeolite support has no impact on its porosity. Also, the metal loading and dispersion are very similar for all three catalysts. A summary of physicochemical properties of the catalysts and their performance in hydrodeoxygenation of m-cresol is given in Table Q2. Considering the given information, answer the following questions: a) Discuss the type of selectivity that is represented in this reaction scheme.
