已知向量组 I ：$\alpha_1, \alpha_2, \alpha_3, \alpha_4$ 线性无关，则线性无关的向量组是（ ）。
A
$\alpha_1+\alpha_2, \alpha_2+\alpha_3, \alpha_3+\alpha_4, \alpha_4+\alpha_1$
B
$\alpha_1-\alpha_2, \alpha_2-\alpha_3, \alpha_3-\alpha_4, \alpha_4-\alpha_1$
C
$\alpha_1+\alpha_2, \alpha_2-\alpha_3, \alpha_3+\alpha_4, \alpha_4-\alpha_1$
D
$\alpha_1-\alpha_2, \alpha_2+\alpha_3, \alpha_3+\alpha_4, \alpha_4+\alpha_1$
E
F
