options A  and B
Step-by-step explanation:
the ratio between the lengths of the two legs of a 30-60-90 triangle
General ration of 30-6- 90 degrees triangle is
x : xsqrt(3) : 2x
When x=1 the ratio becomes 1 : 1 sqrt(3)
when x= 2sqrt(3) the ratio becomes 
It becomes 
Two sides of 30-60-90 triangle cannot be equal
so option c  and option D are not possible
sqrt(2) is also not possible  because we have sqrt(3) in general ratio
