If the matrix A = $\left[\begin{array}{ccc}a & 5 & b \\ -5 & 0 & 4 \\ 7 & c & 0\end{array}\right]$ is skew-symmetric, then the value of a, b and c are:

Options:

a = 2, b = 4, c = 7

a = -1, b = 0, c = 3

a = 0, b = -7, c = -4

a = 0, b = 7, c = 4

Correct Answer:

a = 0, b = -7, c = -4

Explanation:

The correct answer is Option (3) → a = 0, b = -7, c = -4
