It should be heart shake because it starts at the bark and towards the pith. In the other hand, in star shakes starts at pith and crack gets towards the bark.

Star shakes is the right answer crack from outside (bark) to inside (pith) is star shakes.

Heart shake is from inside (pith) to outside (bark).

Cup shake crackes are formed b/w the annular rings and these cracks seperate the annular rings partially.

Ring shakes similar to cup shakes but the seperation b/w the annular rings is 100%.
