Option 1 is the normal way, opt 2 requires more cables and fluid.
On a mk 3 escort there are as standard 4 lines from the mc, one for each corner, ie option 2. Option 2 is also usually plumbed in diagonally so if like you say, you lose the back right you will also lose the front left, but you'll have the other 2 braking still ( admittedly with some sponginess and longevity of pedal) so you have opposite wheels of each axle braking, ie diagonally across the car, so you can still brake straight and under control. Having any 2 brakes t-ed to the same mc outlet is dangerous unless you plumb them diagonally ( as per all modern cars) so that you can brake straight in the event of a circuit failure.
