What happens when a positively charged rod is held near a metal sphere?

Metal sphere A is initially neutral. A positively charged rod is brought near, but not touching. Is A now positive, negative, or neutral? I would really appreciate anyone who can give me an answer and explain why it works that way!

1. that part of A will be negative since the positive rod repels any local positive charge.
2. wen we brng a charged rod in frnt of a metallic sphere the it will induces -ve charge du to induction
3. If A is not connected to anything else, A remains neutral overall because of the conservation of charge. But there is separation of charges; negative charges are attracted to the side nearer the rod, and an equal positive charge is repelled to the other side. The ref. describes this phenomenon of charging by induction using a two-sphere system rather than a single sphere. The principle the same for a single sphere.
