Let A be a \(3\times 3\) matrix with \(\det (\mathrm{A})=4\). Let \({\mathrm{R}}_{\mathrm{i}}\) denote the \({\mathrm{i}}^{\text{th }}\) row of A. If a matrix B is obtained by performing the operation \({\mathrm{R}}_{2}\to 2{\mathrm{R}}_{2}+5{\mathrm{R}}_{3}\) on 2A, then \(\det (\mathrm{B})\) is equal to:
