vu que, a la lumiere de, compte tenu de

[alan gould]

...leur situation actuelle..."

these 3 could all b used to say "in light of their current situation..." 

"vu que" is the shortest and therefore probably the most used since it's the only one i'd heard of.  are all 3 used in conversation?  Tx

[Chantal Savignat]

"vu que..." and "compte tenu de..." are used in conversation.

"à la lumière de ..." is not used in conversation.
