NL50: Help me play this flopped str8 OOP

[chesspain]

Bodog full-table. I have a little over $50, and everyone in the hand has me covered.

No good reads, other than EP seems reasonable, whereas the Button is a calling station.

Preflop: SB posts $0.25. chesspain is BB with J [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/spade.gif[/img].
1 fold, EP calls $0.50, 2 folds, LP calls $0.50, 1 fold, Button calls $0.50, <font color="red">SB raises to $1</font>, chesspain calls $1, EP calls $1, LP calls $1, Button calls $1.

Flop: ($5) 9 [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/heart.gif[/img] K [img]/images/graemlins/diamond.gif[/img] <font color="blue">(5 players) </font>
<font color="red">SB bets $0.50</font>, chesspain...

a) Calls?
b) Raises to $2.50?
c) Raises the pot to $5?
d) Pushes?
