A short column of external diameter $D$ and internal diameter $d,$ is subjected to a load $W,$ with an eccentricity $\text{'}$e$\text{'},$ causing zero stress at an extreme fibre. Then the value of $\text{'}e\text{'}$ must be

$($A$)\frac{D^2+d^2}{8D}$

$($B$)\frac{D^2-d^2}{8D}$

$($C$)\frac{D^2+d^2}{8D}$

$(1)\frac{D^2-d^2}{8D}$
