Consider the line x = y = z and the line 2x + y + z – 1 = 0 = 3x + y + 2z – 2 then
(a) The shortest distance between the two lines is 1/√2
(b) The shortest distance between the two lines is √2
(c) plane containing 2nd line parallel to 1st line is y – z + 1 = 0
(d) The shortest between the two lines is √3/2
