Solution

The correct options are
A $|_{Q P} | = | \to V_{Q} P =$ constant
C $\to V_{Q} P$ toward origin
In position- time graph
$V = \frac{d x}{d t}$
Body P and Q follow straight line, slope is constant.
$V_{p} =$ constant, $V_{Q} =$ constant
Now,
$| {\to V}_{P Q} | = {\to V}_{p} - {\to V}_{Q} =$ constant
$| {\to V}_{Q P} | = {\to V}_{Q} - {\to V}_{P} =$ constant
The correct option is A and C.
