A hot medium is characterised by

A) Non mechanical components

B) Low Audience participation

C) It envelopes only one sense

D) Large amounts of information supplies

E) High audience participation

Choose the correct answer from the options given below:

The correct answer is B, C and D only.

Marshall McLuhan, a renowned media theorist, classified media into two categories: "hot" and "cool" media. This classification is based on the sensory details provided by the medium and the level of engagement required by the audience.

Let's analyze the characteristics of a hot medium step-by-step:
1. Envelopes a single sense (High Definition): A hot medium extends one single sense in "high definition." High definition refers to a state of being well filled with data. For example, print envelopes the visual sense with highly defined symbols, and radio envelopes the auditory sense. Therefore, statement C ("It envelopes only one sense") is correct.
2. Large amounts of information supplies: Because a hot medium provides high-definition content, it supplies a large amount of information directly to the user, leaving little to be filled in by the receiver. Therefore, statement D ("Large amounts of information supplies") is correct.
3. Low audience participation: Since the medium is loaded with information, the audience has to do very little cognitive work to complete or interpret the message. Thus, the level of audience participation is low. This makes statement B ("Low Audience participation") correct, while statement E ("High audience participation") is incorrect.
4. Mechanical components: Hot media are typically products of mechanical reproduction and technological structures (like print, photography, and radio), meaning statement A ("Non mechanical components") is incorrect.

Thus, the statements that characterize a hot medium are B, C, and D.
