Answer:
The correct answer is hot, dense points; each smaller than an atom
Explanation:
The big bang theory was proposed to suggest the expansion of the universe by describing the origin of all components of the universe and it's planetary bodies. It suggested that the whole universe was in a state of high temperature and highly dense points (which were smaller than atoms) but continuously expanded by cooling down which gave rise to the formation of subatomic particles, atoms e.t.c.
