Answer:
there is a large number of buyers and sellers
firms in the industry produce and sell a homogeneous product
there are insignificant barriers to industry entry or exit.
Step-by-step explanation:
A perfect competition is characterised by many buyers and sellers of homogenous goods and services. There are no barriers to entry or exit of firms so firms earn zero economic profit in the long run. Prices are set by the forces of the demand and supply so firms and customers are price takers.
Because one firm has greater output than other firms, it means that the firm has greater market power than other firms so this violates the assumption that there are many firms
If goods are homogenous, it means they are the same in every respect and so must have the same quality. So if products have different quality, they violate the homogeneity assumption.
The government restricts the number of cabs that can operate. This means there are barriers to entry of firms and this violates the "there are insignificant barriers to industry entry or exit" assumption
