In a potentionmeter experiment, when three cells A, B and C are connected in series, the balancing length is found to be 740 cm. If A and B are connected in series, balancing length is 440 cm and for B and C connected in series, it is 540 cm. The emf of `E_(A),E_(B)` and `E_(C)` are respectively (in volts)

A

`1,1.2 and 1.5`
