When do the laws of supply and demand have less effect on prices?

a) when a good or service is new
b)when outside factors cause changes (my choice)
c) when buyers dislike the prices that sellers change
d) when sellers want to make more money

It seems like b is the best, although I think there is supply and demand involved in that too.

Its d

The answer is D

It's D, just took the practice.

WHAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

b can be true, depending on the outside factors. Coming to mind, is government price controls.

the question says which is LEAST

The answer is b

I HAVE NO IDEA

Don't just say its D or B, its different for everyone you have to say the actual answer
