In a meter bridge the point $D$ is neutral point as shown in the figure.
A
The meter bridge can have no other neutral point for this set of resistances
B
When the jockey contacts a point on meter wire left of $D$, current flows to $B$ from the wire
C
When the jockey contacts a point on the meter wire to the right of $D$, current flows from $B$ to the wire through galvanometer
D
When $R$ is increased, the neutral point shifts to left
