Question

True ? False 

It would be hepful if you  provide an explanation of why it is is True or False. 

(a) If A is an m x n matrix and R is the reduced echelon form of A,
then col(A) = col(R). (Here, col(A) means the column space of A.)
%3D
(b) If A is an m x n matrix and R is the reduced echelon form of A,
then dim(col(A)) = dim(col(R)).
%3D
(c) If matrices A and B are row equivalent, the row(A)
(Here, row(A) means the row space of A.)
= row B).
(d) If A is a 6 x 8 matrix with exactly 2 non-pivot columns, then the
pivot columns of A form a basis of R6.
(e) If A is a 6 x 8 matrix such that dim(row(A)) = 5, then the nullity
of At equals 2. (Here, Tow(A) means the row space of A.)
