Reflux ratio is L/D.
At infinite reflux D = 0 overhead product is zero answer B is correct at D = 0 and w = 0 both operating lines becomes Y = X which is the equation of diagonal.
At infinite reflux D = 0 overhead product is zero answer B is correct at D = 0 and w = 0 both operating lines becomes Y = X which is the equation of diagonal.

This answer is wrong it should be "c" because when we see at the operating line for enriching section by McCabe - Thiele method it produces the equation of the diagonal.

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.
So Option (C) is right.

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.

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.

Both options A & B are correct for the condition of Infinite Reflux Ratio.
So, The Right Answer is Option C.
So, The Right Answer is Option C.

B is correct because at infinity reflux ratio product will be zero.

Yes, you are right @Mr. Amit Binwal. The correct option is (B).

It should be option C. Because intercept became zero.
