Answer:

The answer is "Option c".

Explanation:

A mobile phone is a telecom device, which uses radio signals around an internet-connected area but is served at the same fixed location with a cell tower or transmitter, enabling calls to be transmitted electronically across a wide range, to a fixed over the Internet. By increasing the amount and size of layers within the same market area, the total size of the overall system is improved, and the wrong choices can be described as follows:

  • In option a, It is wrong because it can't reuse radio wave frequency.
  • In option b, It decreases the size of the cell, that's why it is incorrect.
  • In option d, It reduces the size of the cells, which increases the capacity of the smartphone and it also decreases the total time of the device, that's why it is wrong.

while(num != -9999)

{

total+=num;

num=scan.nextDouble();

}

if(total<=budget)

{

System.out.println("under budget by ");

System.out.println(budget-total);

}

else

{

System.out.println("over budget by ");
