Find relation between modulus

If

Y $\to$ young's modulus

K $\to$ Bulk modulus

$\eta$ $\to$ modulus of rigidity

(1) $K={\eta Y\over9\eta-3Y}$

(2) $K={\eta K\over9\eta-3K}$

(3) $K={\eta Y\over9\eta+3Y}$

(4) $K={\eta K\over9\eta+3K}$

If

(2) $K={\eta K\over9\eta-3K}$

(3) $K={\eta Y\over9\eta+3Y}$

(4) $K={\eta K\over9\eta+3K}$
