alleryWhich of the following statements about rank is given in the chapter?
ARank changes under every elementary transformation
BNo skew-symmetric matrix can be of rank 1
CRank of $A$ is always greater than rank of $A'$
DEvery zero matrix has rank 1
Answer & Solution
Correct answer: B. No skew-symmetric matrix can be of rank 1
The listed properties state that rank remains unchanged under elementary transformations, no skew-symmetric matrix can have rank 1, and rank of $A$ equals rank of $A'$.
**Hence option B is correct.**
