The graph between two temperature scales `A` and `B` is shown in Fig. Between upper fixed point and lower fixed point there are `150` equal divisions on scales `A` and `100` on scale `B`. The relation between the temperature in two scales is given by_
A. `(t_(A)-180)/100=t_(B)/(150)`
B. `(t_(A)-30)/150=t_(B)/(100)`
C. `(t_(B)-180)/150=t_(A)/(100)`
D. `(t_(A)-40)/100=t_(B)/(180)`
