A body of mass 4 kg experiences two forces $$\vec{F_1} = 5\hat{i} + 8\hat{j} + 7\hat{k}$$ and $$\vec{F_2} = 3\hat{i} - 4\hat{j} - 3\hat{k}$$. The acceleration acting on the body is:

A

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

B

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

C

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

D

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