Solution

The correct option is A $\frac{\partial^{2} E}{\partial x^{2}} = \frac{1}{c^{2}} \frac{\partial^{2} E}{\partial t^{2}}$
The equation of electromagnetic wave propagating along x direction in vaccum is: $\frac{\partial^{2} E}{\partial x^{2}} = \frac{1}{c^{2}} \frac{\partial^{2} E}{\partial t^{2}}$
