Answer
# 3
In UML Activity diagram is used for functional modeling
while sequence diagram is used to dynamic modeling purpose.

A typical workflow can be repersented by activity diagram
while sequence diagram is more about exploring into use
case by showing intercation between objects.

Note: Activity diagram also repersents an object role in
workflow like sequence diagram but level of repersenation
is not dynamic like sequence diagram repersentation.

for example: Object lifeline and sequence of interaction
is detailed in sequence diagram while activity diagram does
not show such detail about an object.
