Answer- The correct answer is E ie., A and B only. If the number
of physicians rises in a particular area then there will be more
supply of physicians and thus it may lead to decrease in demand and
hence the demand will be affected. Increase in the number of
physicians is a part of factors other than price. When the number
of physicians rise the price will change and hence the demand will
also be affected ie., it may rise or fall as per law of demand. But
if the the physicians face decline in payment then providing of
same or more services may not lead to increase or decrease in
demand. It will just add to the value of the services provided as
the primary motive of people to bisit a physician is to get medical
help.
