Which is the best example of ICT making communication faster?

Correct answer: Sending an email message within seconds

The governing concept is the speed advantage of digital communication. Email converts a written message into digital data and transmits it through a network, often reaching the recipient within seconds, subject to connectivity and service availability. Option A is therefore the best example. Postal delivery takes longer, storing paper does not communicate the information, and visiting without sending a message is not an example of faster ICT communication.
