Electrostatic Induction Steps:

• Positively charged rod near left side of neutral metal ball induces charge separation.
• Electrons in conductor move toward rod, making left side negative.
• Positive charges shift to right side, away from rod.
• Total charge remains zero, so left and right charges are equal in magnitude but opposite.

Why C is correct:

• Induction law requires opposite charges on near (negative) and far (positive) sides with equal magnitudes for net zero charge.

Why the others are wrong:

• A: Both negative violates net zero charge conservation.
• B: Identical to C, but if distinct, assumes incorrect side assignment.
• D: Reversed polarities contradict attraction of negatives to positive rod.

Final answer: C
