The answer should be RAM = Random Access Memory
RAM memory is used to store current data while the computer is on. Bear in mind that after the computer is shutdown all data in RAM is lost.

<h2>Option D: Watermark refers to semitransparent text or a faint object that appears behind the document content.</h2>
Explanation:
Footer: This is a text which appears in the bottom of every page. Mostly page numbers and the name of the publisher or the company name will be in the footer.
Page Color: This represents the color of the page
Page border: This option provides border to the page. The border can be thin or thick according to the requirement.
Watermark: This is the right answer. A watermark is added such that your content cannot be used by anyone else without permission. When you copy the text, the water mark also gets copied, thus avoiding plagiarism.
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")
