Answer 1

Right option is (a) 9.79

Best explanation: Given the line is of length 10 inches present on profile plane and ends are at 5 and 3 inches away from vertical plane. As we imagine the projection planes we can get the front view and distance relation as given here. √(10^2-2^2 ) = 9.79 inches.
