Answer:
Option A is the correct answer for the above question.
Step-by-step explanation:
Social networking sites help people to communicate with each other like in a real environment but they are sitting with a great distance with each other. It helps to add people globally and connect them to share the information.
If a person has some problem then he can get the result easily because everyone has some different knowledge related to a different topic and a person can find the solution if there are more people to solve his query. option 'A' also states the same. hence it is a correct answer because the above question asked which option can be researched for social networking websites. while the other is not because--
- Option B states that social websites will help for a research project but the people of social networking sites are not a researcher so it can not help in research.
- Option C states that it is used for statistical knowledge which is not correct.
- Option D states that it is used for original research which is also not correct.
