The three adjacent surfaces of cuboid are x sq. unit, y sq. unit and z sq. unit. The length of its one of the diagonal is Option 1 `((xy)/z+(yz)/x+(zx)/y)^(1/2)` Option 2 `( (z x)/ y + (x y)/ z + (y z)/ x )^(1/2)` Option 3 `((x y)/ z + (y z)/ x + (z x)/ y )` Option 4 `( (z y)/ x + (y z)/ x + (x y)/ z )`

Options

A. `((xy)/(z) + (yz)/(x) + (zx)/(y))1/2`
B. `((z)/(xy) + (x)/(yz) + (y)/(zx))1/2`
C. `((xy)/(z) + (yz)/(x) + (zx)/(y))`
D. `((z)/(yx) + (y)/(zx) + (x)/(yz))`
