The answer would be B. An organic shape.
A whole note lasts for 4 beats taking up a whole measure of 4 beats. This means you would play and hold the not for 4 beats. A whole rest lasts for four beats. A whole rest instructs you not to play for 4 beats. I do not think you can include a rest or a whole note in a rhythm because in this rhythm there is only two measures and if we add a whole rest and a whole note then i think it won’t sound like a rhythm
