Explanation:
In the For-each loop, it is used for traversing items in a sequence is the control flow expression. It typically required a loop becomes referred to it as an enhanced loop for iterating its array as well as the collection elements. This loop is a version shortcut that skips the need for the hasNext() method to get iterator and the loop and over an iterator, and the incorrect choice can be determined as follows:
- In choice A, it is wrong because it can't reverse the array element.

Answer:
b. will be lower if consumers perceive mobile phones to be a necessity.
Explanation:
The price elasticity of demand is described as the percentage variation in the demanded quantity of service or goods divided by the change in the percentage of the price. And henceforth it describes the responsiveness of the demanded quantity to a price change. And now if the mobile phones are thought of as being the necessity then the price will increase as demand will increase, and hence the price elasticity of demand will be lower. And if there is an improvement in the production technology then the price will be lowered, and hence price elasticity of demand will be less as the change in the percentage of the price will be negative. And the exact definition of it as we have described above. Hence, b is correct options.
