Question
Determine whether the statement below is true or false. Justify the answer.
If x is a nontrivial solution of Ax = 0, then every entry in x is nonzero.
Choose the correct answer below.
O A. The statement is false. A nontrivial solution of Ax = 0 is a nonzero vector x that satisfies Ax = 0. Thus, a nontrivial solution x can
have some zero entries so long as not all of its entries are zero.
O B. The statement is true. A nontrivial solution of Ax=0 is a nonzero vector x that satisfies Ax= 0. Thus, a nontrivial solution x cannot
have any zero entries.
C. The statement is true. A nontrivial solution of Ax = 0 is a nonzero vector x that satisfies Ax=0. Thus, a nontrivial solution x can
have some zero entries so long as not all of its entries are zero.
D. The statement is false. The only solution of Ax = 0 is the zero vector. Thus, a nontrivial solution does not exist.
