simplify: square root (4/3)-square root (3/4)

A. 2-sqaure root(3)/2 square root (3)
B. square root (7/12)
C. square root (3)/6
D. 2/square root (3)

which answer?

this is what i got square root (16/12)- square root (9/12)= square root (7/12)

√(4/3) - √(3/4)

= 2/√3 - √3/2
LCD = 2√3

= (4 - 3)/(2√3)
= 1/(2√3)
let's rationalize:
1/(2√3) * √3/√3
= √3/6

looks like c)
