Answer 1

Answer: (B)

$\frac{ dx }{ dt }=$ slope $\geq 0$ always increasing
(A - II)
$\frac{ dx }{ dt }<0$; and at $t \rightarrow \infty \frac{ dx }{ dt } \rightarrow 0$
(B - IV)
$\frac{ dx }{ dt }>0$ for first half $\frac{ dx }{ dt }<0$ for second half.
(C - III)
$\frac{ dx }{ dt }=\text { constant }$
(D - I)
