It's C. It is the Islamic word for an internal struggle against evil or a physical struggle with non-Muslims.

The word "jihad" comes from the arabic language and it means "to strive or struggle". We apply this word to striving to be a better person or to struggle with our faith and striving to make it stronger. Back in time, during the time of Muhammed (peace be upon him), Jihad meant the same thing, but it also applied to defending their nation from the attacks of the other Arab clans (one of which is known as the Quraysh). Hence "struggling and striving" to defend their nation. 

The way some radical "muslim" terrorists use it today is not right at all. That's not what Islam teaches, and those terrorists are not really considered Muslims by other Muslims and Muslim scholars. We disown those people as they are putting our religion in a bad light. 

Also, on a side note, please don't always just blindly listen and believe what the media says. Please do research on your own and you will find that how the media portrays Islam is not true. It is actually a very peaceful religion. In the Quran (the holy book of Islam) a comparison is made that says if you were to unjustly kill one person, it is as if you have killed all of humanity (the level of sin you receive for it) and if you save the life a single person it is as if you have saved all of humanity (the level of reward and blessings you get for it). 

Thanks for reading this. I'm glad I got to answer this question for you. Good luck and have a beautiful day!
