Which one of the following equalities correctly states the distributive property of the dot product for any vectors a, b, c\mathbf{a},\,\mathbf{b},\,\mathbf{c}? (a) (a+b)⋅c=a⋅b+b⋅c(\mathbf{a}+\mathbf{b})\cdot\mathbf{c}=\mathbf{a}\cdot\mathbf{b}+\mathbf{b}\cdot\mathbf{c} (b) a⋅(b+c)=a⋅b−a⋅c\mathbf{a}\cdot(\mathbf{b}+\mathbf{c})=\mathbf{a}\cdot\mathbf{b}-\mathbf{a}\cdot\mathbf{c} (c) a⋅(b+c)=a⋅b+a⋅c\mathbf{a}\cdot(\mathbf{b}+\mathbf{c})=\mathbf{a}\cdot\mathbf{b}+\mathbf{a}\cdot\mathbf{c} (d) (a+b)⋅c=a⋅c+b⋅a(\mathbf{a}+\mathbf{b})\cdot\mathbf{c}=\mathbf{a}\cdot\mathbf{c}+\mathbf{b}\cdot\mathbf{a}
