  4. A carbonyl compound P, which gives positive iodoform test, undergoes reaction with Me Mg Br followed by dehydration to give an olefin Q. Ozonolysis of Q leads to a dicarbonyl compound R, which undergoes intramolecular aldol reaction to give predominantly S. P ->[1. MeMgBr][ underset3.H2SO4, Δ2.H+, H2O] Q ->[1.O3][2.Zn, H2O] R ->[1.OH-][2.Δ] S The structure of the product S is
