A body of mass $4 \mathrm{~kg}$ experiences two forces $\vec{F}_1=5 \hat{i}+8 \hat{j}+7 \hat{k}$ and $\overrightarrow{\mathrm{F}}_2=3 \hat{i}-4 \hat{j}-3 \hat{k}$. The acceleration acting on the body is :

$2 \hat{i}+\hat{j}+\hat{k}$

$4 \hat{i}+2 \hat{j}+2 \hat{k}$

$-2 \hat{i}-\hat{j}-\hat{k}$

$2 \hat{i}+3 \hat{j}+3 \hat{k}$
