Option: 2

\omega(\vec{\mathrm{K}} \times \vec{\mathrm{E}})


Option: 3

\vec{\mathrm{K}} \times \vec {\mathrm{E}}

The magnetic field vector will be in the direction of  \hat{\mathrm{K}} \times \hat{\mathrm{E}}

\\ \text{magnitude of }B=\frac{E}{C}=\frac{K}{\omega} E \\ Or \ \vec{\mathrm{B}}=\frac{1}{\omega}(\vec{\mathrm{K}} \times \vec{\mathrm{E}})
