Sublattice of a lattice

Multi tool use
$begingroup$
Show that for any two lattice bases $B in mathbb{R}^{d times k}$ and $C in mathbb{R}^{d times n}$, the first generates a sublattice of the second $(L(B) subseteq L(C))$ if and only if there is an integer matrix $U in mathbb{Z}^{n times k}$ such that $B = CU$.
