A line makes the same angle \( \theta \), with each of the \( x \)
\( \mathrm{P} \) and \( z \)-axis. If the angle \( \beta \), which it makes with
W \( y \)-axis, is such that \( \sin ^{2} \beta=3 \sin ^{2} \theta \), then \( \cos ^{2} \theta \) equals.
(1) \( 2 / 5 \)
(2) \( 1 / 5 \)
(3) \( 3 / 5 \)
(4) \( 2 / 3 \)
