Answer:
The following are the solution to the given points:
Step-by-step explanation:
for point A:
The set A is not part of the subspace
for point B:
The set B is part of the subspace
for point C:
In this, the scalar multiplication can't behold
∉ C
this inequality is not hold
The set C is not a part of the subspace
for point D:
The scalar multiplication s is not to hold
∉ D
this is an inequality, which is not hold
The set D is not part of the subspace
For point E:
The is the arbitrary, in which
is arbitrary
The set E is the part of the subspace
For point F:
The arbitrary so, they have
as the arbitrary
The set F is the subspace of
