Spell-like abilities, number of uses

[tanostimewalker]

I'm at little bit confused about the notation of number of uses pr spell like abilities...

For an example
a dretch has the following:
Spell-Like Abilities (CL 2nd) 1/day-Cause Fear (DC 11), Stinking Cloud (DC 13), Summon (level 1, 1 dretch 35%)

Does that mean it can cast cause fear and stinking cloud once a day(as if its a wizard)
Or is it like a sorcerer(so it can "cast only one spell", and it has to be one of the three?

Pretty sure it's each of them 1/day
