I think it is option C.

The operating line of only the rectifying section coincides with the diagonal line, and not both the operating lines, so B is correct I think.

It should be option C. Because intercept became zero.

C is the correct answer, according to McCabe-Thiele method the top operating line is plotted between [0, Xd/ (R+1) ] to (Xd, Xd) and at an infinite reflux ratio.

C is the right answer. If the reflux ratio is increasing than a number of plates is minimum so that both the operating lines coincide with diagonal.

Both options A & B are correct for the condition of Infinite Reflux Ratio.

So, The Right Answer is Option C.

C is the right answer because in the Total reflux condition minimum number of plates and both operating lines coincide with the diagnosis.

So Option (C) is right.
