Two semi-infinite dielectric regions are separated by a plane boundary at y = 0. The dielectric constants of region 1 (y< 0) and region 2 (y>0) are 2 and 5, respectively. Region 1 has uniform electric field $$\overrightarrow E=3{\widehat a}_x\;+\;4{\widehat a}_y\;+\;2{\widehat a}_z$$, where $${\widehat a}_x$$, $${\widehat a}_y$$, and $${\widehat a}_Z$$ are unit vectors along the x, y and z axes, respectively. The electric field in region 2 is
A
$$3{\widehat a}_x\;+\;1.6{\widehat a}_y\;+\;2{\widehat a}_z$$
B
$$1.2{\widehat a}_x\;+\;4{\widehat a}_y\;+\;2{\widehat a}_z$$
C
$$1.2{\widehat a}_x\;+\;4{\widehat a}_y\;+\;0.8{\widehat a}_z$$
D
$$3{\widehat a}_x\;+\;10{\widehat a}_y\;+\;0.8{\widehat a}_z$$
