In this paper, we study the oscillatory behavior of the solutions of the delay differential equation of the form \[ \left(\frac{1}{r(t)}y^{\prime }(t)\right)^{\prime }+p(t)y(\tau (t))= 0. \] The obtained results are applied to n-th order delay differential equation with quasi-derivatives of the form \[ L_nu(t)+p(t)u(\tau (t))=0. \]
