I think the answer is C that what i think ;;:;/)
Given:
Circle C and circle R are similar.
The length of arc AB is 
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s, r and 
is
where,
s be the length of the arc
r be the radius
be the angle.
Now,
For circle C
Taking r = 4
According to the problem,
or, 
[ eliminating from both side]
or, 
or, 
Again,
For circle R
Taking, r = 6 and we get,
The length of arc QP is
or, 
Hence,
The length of QP is 
. Option C.
