Can you put the paragraph up so we can help you
I believe its A. Demonstrate responsibility making the restrictions unnecessary .
B is correct, "<span> Christina and I went to the same summer camp for years (since we were 8)" </span>parentheses are used when you have some extra information you want to add, but its not completely necessary. Like how they started going to the same summer camp when they were 8, you can still read the sentence fine without it, but it's a nice piece of information.
Google overcame its competitors because the developers knew how to market and knew how to make a product that consumers wanted. In the early days of the internet, search engines where filled with adds, links, tools like calculators and calendars. While having links to Facebook or Reddit, and having the calculators and calendars seemed helpful, it crowded the page. Those search engines had too much going on to the point it became unhelpful. Google understood that people wanted a search engine that had its purpose and did it well. It's simple, does it's job, and it doesn't overwhelm the consumer when they want to look something up.
Think of it this way, if you're trying to look up a recipe, do you want to go to the page that had 20+ other links and flashy colors and pop up adds, or a simple search bar that will take you right where you need to go with no distractions?
