Of the options given here, the best answer is that the Department of Defense is in charge of protecting the United States from external threats.  However, I would suggest that you check your class materials to see if your instructor wants to see a different answer.

At the Department of Defense’s website, their mission is given as follows. 

The mission of the Department of Defense is to provide the military forces needed to deter war and to protect the security of our country.

This definition of the department’s mission does not match exactly with any of the options you have provided.  However, I do think it is closest to Option B.

Options C and E are clearly wrong.  The military is mainly about hard power, not soft power.  The Department of Defense is not mainly concerned with homeland security, which has more to do with domestic law enforcement than with military forces.

That leaves Options A, B, and D.  The department does do all of these things to some extent.  However, Options A and D are very narrow activities.  The Department of Defense does more than that.  Therefore, I would choose Option B.
