Answer:
Option A
Explanation:
Given equation of line is,
$\frac{x+2}{2}=\frac{2y-5}{3}, z+1=0$
or $\frac{x+2}{2}=\frac{y-\frac{5}{2}}{\frac{3}{2}},z+1=0$
Hence, DR of a line are $<2 , \frac{3}{2} ,0 >$
Now, $\sqrt{2^{2}+\left(\frac{3}{2}\right)^{2}+0}=\sqrt{4+\frac {9}{4}}=\sqrt{\frac{25}{4}}=\frac{5}{2}$
$\therefore$ DC of a line are $< \frac{2}{5/2}, \frac{3/2}{5/2},0 > or < \frac{4}{5},\frac{3}{5},0>$
