(c) at the center of hollow sphere with charges ditributed uniformly on the surface.?
(d) at the centre of a hollow sphere with the charge on one hemisphere is positive, and the chrage on the other hemisphere is negative.

For the beginning, a convention: The direction of an electric field is defined as the direction in which a positive charge would move in that field.
Keeping this in mind:
(a) no field at all.
(b) I don't understand the question: if you have only 3 charges, how can they be equally positive and negative? Where are they positioned?
(c) no field at all
(d) the field points from the positive towards the negative hemisphere
