Markov blanket

A Markov blanket of a node inside of a graph is the set of its parents, children and children’s parents. In this graph, if we want to compute the Markov blanket of the node $C$, we can see that its parents are $\{A\}$, its children are $\{E\}$ and the children’s parents are $\{D\}$, so the Markov blanket is the set $\{A,E,D\}$.
