## A life-saving medicine without any close substitutes will tend to havea. a small elasticity of demand.b. a large elasticity of demand.c. a small elasticity of supply.d. a large elasticity of supply.

Expert Solution
To determine
Demand elasticity and substitute.

Option ‘a’ is the correct answer.

### Explanation of Solution

Option (a):

Lower the availability of substitute, lesser will be the elastic demand. This is because if the price of the good were to increase, people are left with little or no choice but to pay the higher price for it. Since life saving medicine has no close substitute and it has smaller demand elasticity. Thus, option ‘a’ is correct.

Option (b):

More the availability of substitute, more elastic the demand will be. Since life saving medicine has no close substitute, it does not have larger demand elasticity. So option ‘b’ is incorrect.

Option (c):

More the availability of substitute, more elastic the demand will be, and it does not affect elasticity of the supply. So option ‘c’ is incorrect.

Option (d):

More the availability of substitute, more elastic the demand will be, and it does not affect elasticity of the supply. So option ‘d’ is incorrect.
