Answer:
c)Helium nucleus is the answer you are looking for mate.
Explanation:

At the time of the experiment, the atom was thought to be analogous to a plum pudding (as proposed by J. J. Thomson), with the negatively-charged electrons (the plums) studded throughout a positive spherical matrix (the pudding).
