Who will die first if E pushes the stone?

my attempt:-

DE = √(3²+4²)=5blocks

if DE = 2πR+l(where R is the radius of the sphere) then, there is no chance for D to escape,

if DE not equal to 2πR+l then let be DE = (2πR+l)*k, for any value of k. If k is a integral or any value closer to an integral value, D may not make it alive! For any other value, death of D is uncertain.

In both the cases C will die.
