Arrow represents the duration of activity not scale distance between events.

I think option A is also correct because in a network activity is denoted by an arrow.

I think the dummy activity does not require any time.

Rajarshi said: (Apr 6, 2017)  
Dummy activity doesn't any resource or time for completion. So the correct answer will be D & E.

Muluken said: (Jun 22, 2017)  
Option 'E' can be an answer. Because dummy activity is an activity but which do not require any time frame or the duration is zero unit of time.

Debashis said: (Aug 14, 2017)  
Option E is the answer as dummy activity doesn't consume any time.

A bigger arrow would represent activity with larger duration, same goes for the smaller arrow, so how come D is correct?

@All.

Arrow doesn't represent the amount of duration. We don't treat it the way we treat vectors. It is the basic rule of network diagram.
