Answer:
B. watch instructional videos and turn in assignments online.
Step-by-step explanation:
Digital classroom can be defined as an informal learning process which typically isn't structured and it happens spontaneously. It involves learning by watching videos, reading articles and journals, self-study at home, visiting forums and blogs, etc.
Generally, digital classroom typically involves receiving lectures or tutorials on the web through the use of an internet connection. It usually uses teleconferencing software applications or programs such as Zoom, Hangout, etc., and as such the students do not meet the teachers physically.
Hence, students enrolled in a digital classroom watch instructional videos and turn in assignments online.
