Which of the following statements is correct
(A) The meter bridge cannot be configured to have any 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.
