If a good is a necessity with few substitutes, all others things equal, then demand will tend to: have price elasticity equal to 1. be more price-elastic. be the same as that of a luxury good. be less price-elastic.

the answer is that the demand will be less price-elastic

Explanation:

this is mainly because if a good or a service is a necessity, no matter how the price change, the people will still have to consume it as there are no or a minimum number of substitutions. This limits the options the consumers have to change for another product. Thus, making the demand non elastic.
