Lindlar's catalyst is a palladium catalyst poisoned with lead and quinoline. Due to this, it can only reduce alkynes not alkenes. It reduces alkynes to give the Z ("cis") alkene. Hence, the reaction will give the main product as propene (cis-alkene).
Propene on reductive ozonolysis ((i) O3 (ii) Zn/H2O ) gives ethanol and methanol.
