Options

1. A$\frac{E_0}{C}\left(\frac{\hat{i}-\hat{j}}{\sqrt{2}}\right) \cos \left[10^4\left(\frac{\hat{i}-\hat{j}}{\sqrt{2}}\right) \cdot \vec{r}-\left(3 \times 10^{12}\right) t\right]$
2. B$\frac{E_0}{C}\left(\frac{\hat{i}-\hat{j}}{\sqrt{2}}\right) \cos \left[10^4\left(\frac{\hat{i}+\hat{j}}{\sqrt{2}}\right) \cdot \vec{r}-\left(3 \times 10^{12}\right) t\right]$
3. C$\frac{E_0}{C} \hat{k} \cos \left[10^4\left(\frac{\hat{i}+\hat{j}}{\sqrt{2}}\right) \vec{r}+\left(3 \times 10^{12}\right) t\right]$
4. D$\frac{E_0}{C} \frac{(\hat{i}+\hat{j}+\hat{k})}{\sqrt{3}} \cos \left[10^4\left(\frac{\hat{i}+\hat{j}}{\sqrt{2}}\right) \vec{r}+\left(3 \times 10^{12}\right) t\right]$
