I associate "Tone" with sound frequencies. Tonic solfa being a music example which is basically, I think, using a certain musical key signature such as C major. In a major scale the sequence of "musical intervals" (ie frequency steps) is key note TONE TONE SEMITONE ... TONE TONE SEMITONE.octave higher than keynote.
So, I'd go for a here.

Since torque on right side is more so here it will turn and slip over it
Explanation:
As we know that the block A is placed at distance
d = 50 cm from the hinge at 70 cm mark
So torque due to weight of A is given as
the block B is placed at distance
d = 30 cm from the hinge at 70 cm mark
So torque due to weight of B is given as
Now torque due to weight of the scale is given as
now torque on left side of scale is given as
Torque on right Side is given as
Since torque on right side is more so here it will turn and slip over it
