Which situation would not change a buyers market into a sellers market?

a. more investors decide to put their money into construction

b. if factor of lays off a lot of workers in the area

c. a lot of people decide they want to own

d. the population of a city or a town increases rapidly

I think the correct answer would be more investors decide to put their money into construction. A buyers market is characterized by having an excess supply as compared to the demand. So as the more investors put money into the manufacture of a product supply would increase while demand is lower.
