Find the angle between force \( \mathbf{F}=(3 \hat{\mathbf{i}}+4 \hat{\mathbf{j}}-5 \hat{\mathbf{k}}) \) unit and displacement \( \mathbf{d}=(5 \hat{\mathbf{i}}+4 \hat{\mathbf{j}}+3 \hat{\mathbf{k}}) \) unit.
(a) \( \cos ^{-1}(0.49) \)
(b) \( \cos ^{-1}(0.32) \)
(c) \( \cos ^{-1}(0.60) \)
(d) \( \cos ^{-1}(0.90) \)
