# Why is the “geometry” package passed an unwanted argument?

I am working on a class and cannot figure out why geometry is passed my argument "twocolumn", even though I did not use \RequirePackageWithOptions but only \RequirePackage. Can someone explain to me how I can circumvent this strange behaviour ?

Class file

\ProvidesClass{toto}
\DeclareOption{twocolumn}{}
\ProcessOptions\relax
\RequirePackage{geometry}
\endinput


Main .tex file

\documentclass[twocolumn]{toto}
\usepackage{lipsum}
\begin{document}
\lipsum
\end{document}


Global options are passed to every loaded package and geometry has its own twocolumn option.

If you want to nullify it, do

\ProvidesClass{toto}
\DeclareOption{twocolumn}{}
\ProcessOptions\relax
