Consider an electromagnetic wave propagating in vacuum . Choose the correct statement

1. A For an electromagnetic wave propagating in \(+y\) direction the electric field is \(\vec E = \frac{1}{{\sqrt 2 }}\,{E_{yz}}\,\left( {x,t} \right)\,\hat z\) and the magnetic field is \(\vec B = \frac{1}{{\sqrt 2 }}\,{B_z}\,\left( {x,t} \right)\hat y\) 
2. B For an electromagnetic wave propagating in \(+y\) direction the electric field is \(\vec E = \frac{1}{{\sqrt 2 }}\,{E_{yz}}\,\left( {x,t} \right)\,\hat y\) and the magnetic field is \(\vec B = \frac{1}{{\sqrt 2 }}\,B_{yz}\,\left( {x,t} \right)\hat z\)
3. C For an electromagnetic wave propagating in \(+x\) direction the electric field is \(\vec E = \frac{1}{{\sqrt 2 }}\,{E_{yz}}\,\left( {y,z,t} \right)\,\left( {\hat y + \hat z} \right)\) and the magnetic field is \(\vec B = \frac{1}{{\sqrt 2 }}\,B_{yz}\,\left( {y,z,t} \right)\,\left( {\hat y + \hat z} \right)\)
4. D For an electromagnetic wave propagating in \(+x\) direction the electric field is \(\vec E = \frac{1}{{\sqrt 2 }}\,{E_{yz}}\,\left( {x,t} \right)\,\left( {\hat y - \hat z} \right)\) and the magnetic field is \(\vec B = \frac{1}{{\sqrt 2 }}\,B_{yz}\,\left( {x,t} \right)\,\left( {\hat y + \hat z} \right)\)
