(;W[cp]LB[dp:B][dq:A]C[Does white have a reason for playing this move instead of for example A or B or is it just a matter of style?

Yes. It is an offensive style.
It is up to each player's style.

This move forces black to approach the gomoku(somok in Korean).

(;W[qo]LB[po:A]C[A is of course, is also possible. The low move shows white's will to fight, because black already made a low-move.

Cho Hye Yeon: 
Wow!!
I was surprised, too. I couldn't expect black to play it. What an imagination! 
]
(;W[qq]LB[do:A]C[Did white play this tenuki because it hard to find a good move on the lower side for white? How about A instead for white, is it possible?

This move looks wise. White will decide his strategy depending on black's response.
