A linearly polarized transverse wave is propagating in \( z \) direction through a fixed-point \( P \) in space. At time \( t_{0} \), the \( x \) component \( E_{x} \) and the \( y \) component \( E_{y} \) of the displacement at \( P \) are 3 and 4 units, respectively. At a later time \( t_{1} \), if \( E_{x} \) at \( P \) is 2 units, the value of \( E \) will be
(A) 5 units
(B) \( 8 / 3 \) units
(C) \( 3 / 8 \) units
(D) \( 1 / 3 \) units
