choose

Hello,
I have a question concerning the word 'choose'.
During an oral exam a student is shown 3 options - 3 pictures of restaurants/ flats/ presents, etc. and he is supposed to say which one he would prefer. Are all these sentences ok in this situation? :

Of all these options I'd choose ...
I choose the first picture because...
I am choosing the first option because...
I have chosen the first option because...

Thank you for your help!
Kind regards.
