Solution
The correct option is B Negatively charged
When the neutral metal sphere is touched with the negatively charged metal rod, both of them try to achieve same potential and hence some negative charge flows from rod to sphere for both of them to have negative charges.
Since the total charge is conserved, the sum of the negative charges in them would be equal to the originally present negative charge in the rod.
