     \SetCell[c=2]{c}{This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.}   &  &DE  \\
    \hline
 ABC     &  ABC  &  ABC \\

Answer 1

You need hspan=minimal option:

\documentclass{article}
\usepackage{tabularray}
\begin{document}

\begin{tblr}{
  colspec={|Q[c,0.1\linewidth]|Q[l,0.4\linewidth]|Q[r,0.45\linewidth]|},
  rowspec={|Q[c]|Q[l]|},
  hspan=minimal,
}
  \SetCell[c=2]{l}{This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.This is a text.} &       &  DE  \\
  ABC    &  ABC  &  ABC \\
\end{tblr}

\end{document}
