A

Singular Value Decomposition (SVD)

B

Eigen Decomposition

C

LU Decomposition

D

QR Decomposition

Understanding the Answer

Let's break down why this is correct

SVD splits a matrix into three parts: U, Σ, and Vᵀ. Other options are incorrect because Eigen decomposition finds eigenvalues and eigenvectors of a square matrix; LU decomposition breaks a matrix into lower and upper triangular pieces.
