To express a vector in terms of two other vectors, we need to find the scalar multiples of those vectors that add up to the given vector. From the diagram, we can see that vector 11ea6ebb_72c4_2c77_9d78_89df24692336_TB6213_11 can be written as the difference between vectors 11ea6ebb_72c4_7a9c_9d78_69efcb8b701a_TB6213_11 and 11ea6ebb_72c4_7a9d_9d78_eba1192c4ec3_TB6213_11. Therefore, the answer is B.
