The hard disk drive on Joyce's laptop can store up to 500 GB of data. She usually only saves official documents and a few songs that she listens to while she works. However, when she uses more than three applications at the same time, her laptop responds more slowly. What should she do to optimize her storage?
A. Use an external hard disk drive to store data so that there is more free memory on her laptop's hard disk drive
B. Save all her data on a DVD so that the space on her hard disk drive is completely available to run her applications smoothly
C. Increase the RAM on her laptop so that more space for temporary storage of data is available, hence, increasing the performance
D. Replace her hard disk drive with one that provides lesser storage capacity so that the amount of memory available is optimal and performance is increased
