You've clipped enough of this (and I don't remember the context) that I
can't say whether the .PHONY should be the .o or the .c.
However, your statement "If we keep 2.o as phony, then 2.o is never
rebuilt" is not correct as written. A .PHONY target is ALWAYS rebuilt;
that's what it means to be phony.
