A1, 2, 3 and 4 ✓ Correct

B2, 3 and 4

C1, 3 and 4

D3 and 4

Correct answer: (A) 1, 2, 3 and 4

Explanation

All four statements are true, covering synchronous, asynchronous and the digital divide correctly.

Statement 1 is true because sending and receiving messages at the same time is synchronous communication.

Statement 2 is true because video conferencing is a real time, hence synchronous, technology.

Statement 3 is true because learning from a CD happens at the learner's own time and is asynchronous.

Statement 4 is true because the digital divide names the gap in IT and ICT use between developed and developing, urban and rural groups.

Recognising these terms helps in planning equitable access to technology.
