**No**, if three vectors do not lie in a plane, they cannot give zero resultant.

__Explanation__:

Let **A**,** B and C** be three vectors. If they give zero resultant, then

**A**+**B**+**C**=0

or, **A**= -(**B**+**C)**

Hence, they will produce zero resultant, if **A** is equal to negative of vector (**B**+**C). **The vector (**B**+**C) **lies in the plane of **B **and** C.** Hence, **A** will be equal to negative of (**B**+**C) **if **A**, **B **and **C **all lie in a plane.
