Answer: E. She prefers to shop online because it is more convenient and items are constantly available.
Explanation: The biggest benefit of online shopping is 'convenience' as it can be done from anywhere, at any time and even from our phones as all you need to do so is have a decent internet connection. You don't face problems like the shop is too far or it might be closed.
Also, many times online shopping is cheaper than offline.
Cheap deals and better prices are available online, because products come to you direct from the manufacturer or seller without involving middlemen. Plus, it's easier to compare prices and find a better deal. Many online sites offer discount coupons and rebates, as well.
