Let's analyze the given options to determine the percentage of text messages sent in a day that are spam and viruses. We are provided with four possible choices:
A) 45%
B) 90%
C) 75%
D) 60%
The correct answer to this question is 45%.
This means that, based on the analysis, 45% of text messages sent in a day are identified as spam and viruses. Consequently, if you have a total of 100 text messages, you can expect about 45 of these messages to be unwanted spam or viruses, while the remaining 55 messages would be legitimate.
So the answer is Option A: 45%.
