So the answer is D) 16

Here are the list of all the possible subsets (count them and you'll find that there are 16 subsets)

{mom, dad, son, daughter},
{mom,dad,son}, {mom,dad,daughter}, {mom,son,daughter}, {dad,son,daughter},
{mom, dad}, {mom, son}, {mom, daughter}, {dad, son}, {dad, daughter}, {son, daughter},
{mom}, {dad}, {son}, {daughter},
{}

Note: {} is the empty set
