  • welcome to tex.se! do you really need longtable? is many page long? from table image is seems that tabular* or tabularx can be is sufficient.

  • Your code doesn't compile: You set up the longtable as having a single column, yet you then have a \multicolumn{2}{..}{...} directive. Please make the code compilable -- so that it actually generates the error you're looking to fix.

it is not clear, which table you like to obtain. if the first one, and if the table on the end will longer than one page, than solution can be:

\usepackage{longtable, tabularx}

%-------------------------------- show page layout, only for test

    with \verb+longtable+:
\multicolumn{2}{| c |}{\cellcolor{gray!25} Begin of Table}\\
 A) Something   & B) something j    \\
 C) Something & D) something j\\

with \verb+tabularx+:
\multicolumn{4}{| l |}{What is capital of Canada?}  \\
Berlin   & C &  Ottawa  & A    \\
Rome    & D &  Canberra & B    \\
