1. digital learning does not allow grades, while traditional learning includes grading students.
2. digital learning does not involve teachers, while traditional learning includes teachers.
3. digital learning takes place in a classroom building, while traditional learning exists mostly online.
4. digital learning exists mostly online, while traditional learning takes place in a classroom building.

The answer is 4, but I have to type more.

The correct answer is "4. Digital learning exists mostly online, while traditional learning takes place in a classroom building".

Explanation:

Digital learning is commonly associated with technology and internet, which means that it is mostly done online, although some features may be developed with no internet use, but with technology tools still. Traditional learning is usually related to schools and universities, and mainly developed in classrooms. All the other options are lacking in some way, whether because they are incomplete, or because they mean the opposite of the question.

i guess the correct option is letter a.

use contrasting font sizes, but the same font style
