This application is a static web page that accepts and displays information about the products and services of a company. This information is stored in a database. Which of the following options states the best solution to optimize the application?

a. He needs to reduce the number of floating point operations and load data into the memory before executing instructions, so that the process need not wait for data.

•           b.      He needs to write code that accesses memory sequentially and built custom routines for accessing operating system services.
 
• 1. c. He needs to use large data structure

d. He needs to identify the floating point operations and build custom routines so that the process need not wait for data.
