સૂચિ$-I$ અને સૂચિ$-II$ ને સરખાવો.
નીચે આપેલા વિકલ્પોમાંથી સાચો જવાબ પસંદ કરો.
A
$(A)-(II), (B)-(IV), (C)-(III), (D)-(I)$
B
$(A)-( I), (B)-(II), (C)-(III), (D)-(IV)$
C
$(A)-( II), (B)-(III), (C)-(IV), (D)-(I)$

(JEE MAIN-2023)
Solution
$\frac{d x}{d t}=\text { slope } \geq 0 \text { always increasing }$
$\text { (A – II) }$
$\frac{d x}{d t} < 0 \text {; and at } t \rightarrow \infty \frac{ dx }{ dt } \rightarrow 0$
$( B – IV )$
$\frac{ dx }{ dt } > 0 \text { for first half } \frac{ dx }{ dt } < 0 \text { for second half. }$
$\text { (C – III) }$
$\frac{ dx }{ dt }=\text { constant }$
$\text { (D – I) }$
