0 votes 0 votes Given an m × n matrix with real entries (or entries from any other field) and rank r, then there exists at least one non-zero r × r minor, while all larger minors are zero. Hence answer is option D. Abhisek Das answered Jun 28, 2017 Abhisek Das comment Share Follow See all 0 reply Please log in or register to add a comment.
