All four vectors r1, r2, r3, r4 are linearly dependent. To answer whether r1, r2, r3 are linearly dependent, we need more information on these vectors.

Vectors r1, r2, r3 may constitute either a linearly independent  set (for example, (1,0,0), (0,1,0),(0,01) ) or a linearly dependent set (for example, r1=r2=(1,0,0), r3=2r1=2r3=(2,0,0)). Thus, r1, r2, r3 do not always constitute a linearly independent set, though they may.

If you can represent the sum of given vectors r1, r2 and r3 by a single vector r4 i. e. r4 = r1 + r2 + r3. Then you can say r4 is linearly dependent on r1, r2 and r3 and that r1, r2, r3 and r4 constitute a linearly dependent set of vectors. On the other hand r1, r2 and r3 are linearly independent vectors ANSWER IS r4
