The correct answer is: E-learning

Rationale: It is the networked aspect that makes e-learning different from CBT (using stand-alone computers). Blended learning involves learning using a combination of different methods and technologies: this would be the correct option if the learning support was available from face-to-face tuition, say.

Pitfalls: Learning technologies is fertile territory for exam questions, because there are so many closely-related methods and terms (coaching, mentoring etc).

Ways in: Just about anything with an 'e-' in front of it, these days, is about the Internet - not stand-along computers, so you should be able to rule out computer based training.
