A
$\frac{1}{2}$ a: $\frac{\sqrt{3}}{2} a : \frac{\sqrt{2}}{2} a$
B
$\frac{1}{2} a : \sqrt{3} a : \frac{1}{\sqrt{2}} a$
C
$1 a : \sqrt{3} a : \sqrt{2} a$
D
$\frac{1}{2} a : \frac{\sqrt{3}}{4} a : \frac{1}{2 \sqrt{2}} a$
Solution:
Correct answer is (d) $\frac{1}{2} a : \frac{\sqrt{3}}{4} a : \frac{1}{2 \sqrt{2}} a$
