Which of the following statement is true [J \& K CET 2006]
(a) When the coordinate axes are translated the component of a vector in a plane changes
(b) When the coordinate axes are rotated through some angle, components of the vector change but the vector's magnitude remains constant
(c) Sum of \( \vec{a} \) and \( \vec{b} \) is \( \vec{R} \). If the magnitude of \( \vec{a} \) alone is increased angle between \( \vec{b} \) and \( \vec{R} \) decreases
(d) The cross product of \( 3 \hat{i} \) and \( 4 \hat{j} \) is 12
