Bracket ADO Is Acted on by Forces F and T $\boldsymbol { R }$

Bracket ADO is acted on by forces F and T and couple M (see figure) . Assume that F = 8 N, T = 9 N and M = 12 N ∙ m. Joint coordinates are in meters.The resultant force vector $\boldsymbol { R }$ (in newtons) is:

A) $- 5 \boldsymbol { i } + 7 \boldsymbol { j } + 1 \boldsymbol { k }$
B) $- 3 i + 4 j - 3 k$
C) $- 6 i + 5 j + 4 k$
D) $- 3 i + 6 j + 2 k$
