B. Fewer workers will be needed.

Explanation:

Elastic demand refers to a flexible demand. It is a demand that can increases or decreases due to several factors. If demand is not elastic, it implies it is constant. An increase or decrease in output or price will not affect the quantity demanded.

An increase in productivity means an increase in output per worker. It is the increase in the number of units produced, per hour, per worker. An increase in productivity results in more output in a given period than previously.

If the demand is constant and there is an increase in productivity, only a few workers will be required. The output from the few workers will be high to meet the constant demand.
