Let U be the subspace of R3 spanned by U1​=(1,2,3)⊤, U2​=(2,−1,0)⊤. Let V be the subspace spanned by V1​=(5,0,3)⊤, V2​=(3,1,3)⊤. Is V a subspace of U? Are U and V the same?

a) Yes, V is a subspace of U, and U and V are the same
b) No, V is not a subspace of U, but U and V are the same
c) Yes, V is a subspace of U, but U and V are not the same
d) No, V is not a subspace of U, and U and V are not the same
