True on what David said but also because flutes and oboes react accoustically as open pipes while clarinets react accoustically as closed pipes. This is why the flute and oboe overblow at the octave and the clarinet overblows at the twelfth.
The closed-end cylindrical bore of the clarinet is what causes it to act as a closed pipe and that is why the clarinet can produce the same pitch as the flute or oboe with only half the length of pipe.
Happy Clarineting!

You could throw soprano sax in the mix as well.

The flute acts as a pipe open at both ends, which behaves the same as a vibrating string, i.e. the tube (or the string) contains 1/2 of a complete sound wave.
So in approximate terms (without other complicated considerations) the sound wave for the lowest note for a flute is twice as long as the flute.
The clarinet acts as a tube which is closed at one end and open at the other. It contains only 1/4 of a complete sound wave.
So the sound wave for the lowest note for a clarinet is FOUR times as long as the clarinet.
Now the oboe, like the clarinet, is closed at one end and open at the other, so it could be expected to have a low note like a clarinet. This is not the case because the bore is seriously tapered and this makes it follow a different set of rules, making it behave rather like a flute.
