Greetings!
The correct answers would be Computer, Internet, Electronic, and pretty much anything else that refers to something with being online, or the internet.
Hope this helps you!
Sentence B is the correct option. When using "however" to write a compound sentence, we should write a semi-colon before and a comma after it. When "however" is used at the beginning of a sentence, we should write a comma following it.
In grammar, an interjection is a word used to display emotions, such as surprise, glee, anger, etc. In this case the word "Yummy" is being used to display eagerness to enjoy the dinner that smells so unbelievably good.
Option A, "Yummy", is your correct answer choice.
Hope that helped! =)
