Latex: enumerating in multicols gives unwanted whitespace between lines

Question

I am trying to set up a multiple answer sheet with several short answers, but when I try to use the multicol environment, it creates unwanted whitspace.

The code is

\documentclass[11pt,addpoints]{exam}
\usepackage{amsfonts,amssymb,amsmath, amsthm}
\usepackage{graphicx}
\usepackage{systeme}
\usepackage{pgf,tikz,pgfplots}
\usepackage{multicol}
\pgfplotsset{compat=1.15}
\usepgfplotslibrary{fillbetween}
\usepackage{mathrsfs}
\usetikzlibrary{arrows}
\usetikzlibrary{calc}
\usepackage[shortlabels]{enumitem}
\usepackage{amsmath}
\newcommand{\summation}[2]{\sum\limits^{#1}_{#2}}

    
\textbf{11)} The expression $\frac{\sin{x} + \sin{y}}{\cos{x} + \cos{y}}$ is equal to
    \begin{enumerate}[(A)]
    \begin{multicols}{2}
            \item $\tan{\frac{x + y}{2}}$ % CORRECT
        \item $\tan{\frac{x - y}{2}}$
        \item $2\tan{x + y}$
        \item $2\tan{x - y}$
        \item $2\tan{2 x y}$
        \end{multicols}
    \end{enumerate}

and it looks like this Any advice on how to solve the issue?

I tried using the multicols* environment, but it caused the page to contain only the answer columns.
