A body is a rest at \( x=0 \). At \( t=0 \), it starts moving in the positive \( x \)-direction with a constant acceleration. At the same instant another body passes through \( x=0 \) moving in the positive \( x \)-direction with a constant speed. The position of the first body is given by \( x_{1}(t) \) after time ' \( t \) ' and that of the second body by \( x_{2}(t) \) after the same time interval. Which of the following graphs correctly describes \( \left(x_{1}-x_{2}\right) \) as a function of time ' \( t \) '
