Explanation:

For a contract to be considered as valid , there are several things that needed to happen :

- It contain an agreement between two party or more that listed the obligation of all parties involved. (If party A do X , then Party B will do Y)

- The agreement cannot be illegal/violated the law in anyway.

- It need to have a way to proof the fulfillment of the agreement.

Option C is the only one that fulfill all of these things. Khairil does not necessarily told Luna to 'steal' the ingredient, Luna just have to obtain it. So it doesn't violate any law.
