Force $F$ Is Applied at D Along Line DB and Couple $\boldsymbol { M }$

Force $F$ is applied at D along line DB and couple $\boldsymbol { M }$ is perpendicular to plane ABC. Assume magnitudes F = 20 lb and couple M = 50 in-lb. The moment $\boldsymbol { M } \boldsymbol { A } \text { (in-lb) due to both } \boldsymbol { F } \text { and } \boldsymbol { M } \text { is: }$

A) $37 \boldsymbol { i } - 60 \boldsymbol { j } + 22 \boldsymbol { k }$
B) $- 37 i - 60 j - 22 k$
C) $- 37 i - 60 j - 22 k$ .
D) $- 60 i - 37 j - 22 k$
